Improvement on the reliability of protection function

Any parts and materials applied to the protection relay have limited life time which will bring the degradation to the relay. The degree of degradation will be variable and depend on the purpose, period in use, applied circumstance and unevenness on the performance of each part. MITSUBISHI ELECTRIC CORPORATION design the relay so as to realize that the recommended replaced duration is more than 15 years. However, there may be some possibilities to occur some defects before reaching 15 years due to above mentioned the degree of degradation of parts and materials being depended on the condition in use. To prevent unwanted operation or no operation of relay due to above reasons, it is recommended to apply the relay with self-diagnosis function and/or multiplexing relay system such as dual or duplex scheme.

2. Rating, Specification

2.1. Features (product conforming to IEC60255)

(1) Multi-function

The relay incorporates a variety of protection functions which are required for motor protection.

Therefore, it is possible to protect the feeder with the use of a single relay.

The relay has two Group settings sets. Therefore, it can be used for different purposes, such as

operation/test, or quickly adapted to meet load conditions.

Control of a circuit breaker is possible via the font panel, PC-HMI, or remote communication

(option).

(2) High-precision measuring functions

Measurement functions are enhanced.

Current, voltage, electric power, quantity of electricity, frequency, can be viewed via the front panel

display on the relay or using interface software on a PC.

Fault / Disturbance Recording

The relay stores up to 5 fault / disturbance records which can be used for fault investigations.

Fault record function is the record of analog input values (as RMS) at the time when relay

elements are operated. Disturbance record function is the record of waveform data for the

prescribed period before and after occurrence of fault at sampling rate of 24 samples/cycle.

(3) Selection of communication networks

Modbus (RS485)

Modbus communication function is incorporated as standard.

IEC61850 (Ethernet Station Bus)

An optional communication card will enable communication based on IEC61850 with GOOSE

messaging.

A two-port optical connector or a single port electrical connector is provided. If the optical two-port

connector is selected, HSR (High-availability Seamless Redundancy) and PRP (Parallel

Redundancy Protocol) can be configured to improve the reliability of communication.

(4) Programmable Output Contacts provide flexibility

The configuration of output contact is possible by PLC (Programmable Logic Controller), which

enables to apply the relay to various systems.

(5) Advanced constant monitoring function improves reliability

The relay continuously monitors the electronic circuits and can detect internal component failure,

which enables to improve reliability.

The relays behavior is as follows:

In normal conditions: RUN LED lights.

In abnormal conditions: ALARM LED lights.

During serious abnormal conditions, the protection elements are locked to prevent an

unnecessary output, and the relay fail alarm is issued.

(6) The draw-out Subunit improves maintainability

The provision of an automatic CT shorting mechanism at the time of drawing out the unit makes it very

easy to maintain the relay.

Remarks: This mechanism is installed only in relay devices with current protection element.

3.2. Overcurrent Element

The CMP1-A41D1 Relay has 3 types of overcurrent element, listed in the table below, which achieve fast detection for a fault affecting the induction motor. Also, since the overcurrent element with dependent time characteristic has a switchover function of operating sensitivity and time between the time of motor-startup condition and the time after the completion of motor-startup as shown in Fig. 3-1, it prevents unnecessary operation from the motor excitation inrush currents during motor-startup condition.

OC1 Element (Overcurrent with IDMT/DT Element)

OC1 overcurrent element is applied to detect a fault occurring during the flowing condition of motor excitation inrush current at motor-startup, from the detection of motor-startup to the completion of motor- startup. Therefore, it is necessary to set the sensitivity and dependent time settings so as to prevent the element operation from the motor-startup current. The method for detecting motor-startup is by receiving the closing signal of CB auxiliary contact (52a) for energization of the motor to DI 7 (fixed terminal). Thus, this element is activated when DI 7 is not injected the voltage. In case of the protection of reciprocating motor, a pulsating current induced by motor current would be superimposed on line current. Since the relay input current with pulsating component generates large error in the results of current calculation of the relay, it is provided the averaging function for current calculation on motor rotating cycle to mitigate the pulsating current affection. There are two types of dependent time characteristics, long inverse time and definite time. The internal function block diagram is shown in Fig. 3-2. OC1 Element outputs a detection signal when the detection output is operative and the dependent time characteristic timer (time-limit timer) period has passed. The detection output is operative when input current is greater than the detection current setting, selected from Ope. Curt. or Ope. Curt. x 1.15 by IEC Chr. EN setting. Also, as mentioned above, in case of a reciprocating motor, the current-averaging cycle-number setting (Ave. Cycle) should be set for motor rotating cycle and current-averaging enable/disable setting (Ave. Curt.) should be set to enable (ON). The internal timer (Time-limit timer) counts up in accordance with dependent time characteristic (Ope. Chr.) when current is greater than the operation setting value (Ope. Curt.). A 200-ms reset timer is incorporated to prevent chattering on the contact. In addition, OC1 Element outputs an operating signal only when its enable/disable setting (OC1 EN) is set ON. The setting of OC1 EN = OFF prevents the unnecessary operation of the element.

Setting of Ave. Cycle In case of the protection of reciprocating motor (pumping motor), a pulsating current induced by motor current would be superimposed on the current of electric power system. Since the relay input current with pulsating component generates a large error in the results of calculation in the relay, it is provided the averaging function for current calculation on motor rotating cycle to mitigate the pulsating current. An example of the pulsating current by the reciprocating motor is shown in Fig. 3-5. In Fig. 3-5, the black dash line indicates a motor current of instantaneous values, the blue dash line indicates an envelope of the instantaneous motor current (the calculated peak values when the Ave. Cycle = OFF), and the red solid line indicates the considering the pulsating current (the calculated peak values when the Ave. Cycle = ON). We assume following condition.

The power system frequency sets 60 Hz. The period of the pulsating current black dash line sets about 6 Hz (360 rpm).

The setting Ave. Cycle can be obtained by following equation. (power system frequency) / (frequency of the motor pulsating current) = 60 Hz / 6 Hz = 10 [cycle]

Then, in this example, the 10 cycle is applied as setting Ave. Cycle. And the red solid line should be obtained in Fig. 3-5.

OC2 Element (Overcurrent with IDMT/DT Element)

OC2 overcurrent element is applied to detect a fault after the time at which the motor excitation inrush current disappears after the completion of motor startup. Therefore, it is necessary to make sensitivity and time settings so as to be suitable for motor normal operating condition. The method for detecting conditions for the completion of motor startup is by receiving the CB auxliary contact (52a) signal to DI 7 (fixed terminal) for turning the motor ON/OFF. Thus, this element becomes operable when the signal is applied to DI 7. Also, considering the case of reciprocating motor, OC2 Element provides the averaging function for current calculation on motor rotating cycle to mitigate the pulsating current affection as same as OC1 Element.

OC2 Element provides two types of dependent time characteristics, long inverse time and definite time. The internal function block diagram is shown in Fig. 3-6.

OC2 Element outputs a detection signal when detection output is operative and the time-limit timer period has passed. The detection output is delivered when input current is greater than detection current setting selected by IEC Chr. EN setting of Ope. Curt. and Ope. Curt. x 1.15 by). Also, as mentioned above, in case of a reciprocating motor, the current-averaging cycle-number setting (Ave. Cycle) should be set for motor rotating cycle and current-averaging enable/disable setting (Ave. Curt.) should be set to enable (ON). The internal timer (Time-limit timer) counts up in accordance with dependent time characteristic (Ope. Chr.) when current is greater than the operation setting value (Ope. Curt.). A 200-ms reset timer is incorporated to prevent chattering on the contact. In addition, OC2 Element outputs an operating signal only when its enable/disable setting (OC2 EN) is set ON. The setting of OC2 EN = OFF prevents the unnecessary operation of the element.

Logic Function of 51LR (Locked Rotor) Timer using OC1 and OC2

This characteristic is installed to the 60Hz model of a combination with 5A positive-sequence and 5A zero- sequence. This 51LR function is used for a motor protection against locked running rotor. In the motor starting period, the motor acceleration current is greater than the normal operating current. Therefore using binary input, overcurrent characteristic (OC1 and OC2) is changed. This overcurrent changing function is offered for all models in CMP1-A41D1 series. And, the situation that occasionally need the time delay from OC1 to OC2 is assumed. For such situation, 51LR Ope. Time is set.

OC3 Element (Overcurrent Instantaneous Element)

OC3 is an instantaneous overcurrent element for detecting the large fault current. Also, considering the protection of a reciprocating motor, it provides the averaging function for current calculation as mentioned in the overcurrent element with dependent time characteristic. The internal function block diagram is shown in Fig. 3-8.

OC3 Element outputs a detection signal after the lapse of the operation timer period (Ope. Time) if input current is greater than operation setting value (Ope. Curt.). Also, as mentioned above, in case of a reciprocating motor, the current-averaging cycle-number setting (Ave. Cycle) should be set for motor rotating cycle and current-averaging enable/disable setting (Ave. Curt.) should be set to enable (ON). The internal timer (Time-limit timer) counts up in accordance with dependent time characteristic (Ope. Chr.) when current is greater than the operation setting value (Ope. Curt.). A 200-ms reset timer is incorporated to prevent chattering on the contact. In addition, OC3 Element outputs an operating signal only when its enable/disable setting (OC3 EN) is set ON. The setting of OC3 EN = OFF prevents the unnecessary operation of the element.

OCNEG3 / SPO Element (Single phase-open Detection Element)

Fig. 3-11 shows the internal function blocks of Single Phase Open (SPO) element.

When the single phase open phenomenon is occurred, the unbalance current flows. In general, this

unbalance condition can be detected by Negative-sequence overcurrent element (Device No. 46 which is named OCNEG in this product). Under the single phase open condition, a phase current which concern with a breaking wire goes down. This

element focuses this current behavior and this element consists of under/over-current elements. There is 'Loss Curt.' setting to detect a drop down current. The AND logics after the collation timers make

sure the condition whether or not a single phase open. There is Load Curt. setting to check that it was worked on a normal operating condition before the occurring

of the single phase open phenomenon. To confirm the healthy condition before a fault, there is the average calculation block of 15 minutes. The operation delay timer (2 seconds) is fixed. An off-delay timer of 200 ms is added in order to prevent

chattering of the output contacts. This element is enabled or disabled by the setting (SPO EN).

Note Using this protection element, it is necessary the 3 CT connection. In case of 2 CT connection, this element cannot offer intended operation.

UC1 Element (Undercurrent Element) The internal function block diagrams shown in Fig. 3-12 and Fig. 3-13 explains how UC1 Element works.

[Method 1] In the case where setting is made for Pick up = Pick 1 UC1 Element outputs a deterministic signal after the lapse of the operation timer period (Ope. Time) if input current is less than operation setting value (Ope. Curt.). A 200-ms reset timer is added on the reset side to prevent chattering on the contact. By making an appropriate setting (Output. Sel.), you can specify whether a deterministic signal should be outputted on the basis of operation in more than one phase. Note that a locking capability is provided for UC1 Element in each phase to facilitate the performance of testing on a single-phase input. This locking capability can be set from VFD operation panel or PC tool. In addition, UC1 Element outputs an operating signal only when its enable/disable setting (UC1 EN) is set for ON. If you do not want to use this element, switch the setting to OFF. This will prevent the unnecessary actuation of the element. In regard to UC1-related setting items, anything else does not have to be set.

50BF CBF CBF detecting element

49 JEP0-IL9498 C

CBF Element (CBF detecting element)

The internal function block diagram shown in ! explains how CBF

Function works. CBF Element outputs a deterministic signal after the lapse of an operation timer period (Ope. Time) if a level

assessment of input current in each phase and zero phase vs. operation setting value (CBF Curt. and CBFG Curt.) determines that the input current is greater than the operating level and a trip signal is being received from any of other relays. That is, the function is comprised of a circuit which, when a relay trip signal is received upon the occurrence of an accident but a current continues to flow even after the lapse of a certain duration of time, identifies that there is a faulty condition in the breaker. Make a configuration setting so that a trip signal from any of other relays will be received by D/I (DI8). Note: An optional IE61850 communication card, if installed, makes it possible to receive a trip signal from any of other relays via the GOOSE function. In this case, make a Goose receive setting so that the trip signal will be received by G_TRIP1, G_TRIP2, or G_TRIP3. In addition, CBF Function outputs an operating signal only when its enable/disable setting (CBF EN and CBFG EN) is set for ON. If you do not want to use this element, switch the setting to OFF. This will prevent the unnecessary actuation of the element. In regard to CBF-related setting items, anything else does not have to be set.

Device No. Display name Protective function

49 THOL Thermal Overload element

2 types of operating time characteristic

51 JEP0-IL9498 C

THOL Element (Thermal Overload Element) This element protects the motor against insulation deterioration, damage or the like which could result from

heat generation. Also, considering the protection of a reciprocating motor, it provides the averaging function for current

calculation as mentioned in the OC1 element. There are two types of operating time characteristics, COLD and HOT. Fig. 3-15 shows the internal function blocks of the element.

THOL Element calculates positive-/negative sequence current from a 3-phase current and makes a level

assessment of calculated current value by Equation 1 below vs. operation setting value (Ope. Curt.), and then outputs a definitive signal after the lapse of a time calculated from the characteristic equation for operate/reset time characteristic switchover setting (THOL Sel.) if the calculated current value is greater than or equal to the operation setting value (Ope. Curt.).

( )2 2

1 2.Iop I Neg K I= + (Equation 1)

Where, Iop: Operating value of THOL element I1: Positive sequence current I2: Negative sequence current Neg. K: Negative sequence heat-generation multiplier

As mentioned above, in case of a reciprocating motor, the number of cycles for current-averaging setting

(Ave. Cycle) should be set for motor rotating cycle and current-averaging Use/Non-use setting (Ave. Curt.) should be set to ON. An off-delay timer which corresponds to the COLD/HOT characteristic is added in order to prevent chattering

of the output contacts. Furthermore, this element outputs the definitive signal only when the Use/Non-use setting of THOL element

(THOL EN) is ON. Therefore, when this element is not used, unnecessary operation can be prevented by setting to OFF. It is not necessary to set other setting items with regard to THOL element.

Note Using this protection element, it is necessary the 3 CT connection. In case of 2 CT connection, this element cannot offer intended operation.

Where, IP1 = Initial positive sequence current (0 for COLD characteristic) IP2 = Initial negative sequence current (0 for COLD characteristic) I1 = Positive sequence current I2 = Negative sequence current

COLD characteristic

The COLD characteristic starts computations from when input has exceeded an operating value.

When the input has fallen below the operating value after the delivery of an operating output, the

characteristic resets itself in 200 ms and resets its computations.

On the other hand, if the input has fallen below the operating value with the input becoming higher than

the operating value but not resulting in the delivery of an operating output, the characteristic reduces the

value obtained from its computations.

HOT characteristic

The HOT characteristic always performs computations taking heat accumulation into consideration even if

input remains below an operating value.

DIRG1 Element outputs a deterministic signal after the lapse of the operation timer period (Ope. Time) if the level assessment of zero-phase current vs. operating current setting value (Ope. Curt.) and zero-phase voltage vs. operating voltage setting value (Ope. Volt) determines that the zero-phase current/voltage is greater than the operating level and phase differences of zero-phase current and voltage remain within an operating range A 200-ms reset timer is added on the reset side to prevent chattering on the contact. In addition, DIRG1 Element outputs an operating signal only when its enable/disable setting (DIRG1 EN) is set for ON. If you do not want to use this element, switch the setting to OFF. This will prevent the unnecessary actuation of the element. In regard to DIRG1-related setting items, anything else does not have to be set.

UV1 Element (Undervoltage Element)

Fig. 3-22 shows the internal function blocks of UV1 element. Setting (UVP/UVS SEL) is used to determine whether phase voltage measurement or line (phase to phase) voltage measurement will take place to determine the under-voltage condition. If the selected input voltage is less than the operation setting value (Ope. Volt.), a definitive signal is issued after expiry of the operation timer (Ope. Time). An off-delay timer of 200 ms is added in order to prevent chattering of the output contacts. Setting (UV1 SEL) is used to set whether the operation of the element is based on a single phase voltage measurement or a three phase voltage measurement., To facilitate testing of the single phase operation, a lock function is provided for the UV1 element of each phase. The lock function can be set from the front panel or PC tool. The UV1 element outputs the definitive signal only when the setting of Use/Non-use of UV1 element (UV1 EN) is ON. Therefore, when this element is not used, unnecessary operation can be prevented by setting to OFF. It is not necessary to adjust any other settings with regard to the UV1 element

OV1 Element (Overvoltage Element)

Fig. 3-23 shows the internal function blocks of OV1 element. It is possible to select by setting (OVP/OVS SEL) whether the phase voltage or line (phase to phase) voltage will be used to detect over-voltage. When the selected input voltage is greater than the operation setting value (Ope. Volt.), a definitive signal is output after the preset time on the operation timer (Ope. Time) has expired. An off-delay timer of 200 ms is added in order to prevent chattering of the output contacts. To facilitate the testing of a single phase, a lock function is provided for the OV1 element for each phase. The lock function can be set from the VFD operation panel or PC tool. The OV1 element outputs the definitive signal only when the setting of Use/Non-use of OV1 element (OV1 EN) is ON. Therefore, when this element is not used, unnecessary operation can be prevented by setting to OFF. It is not necessary to adjust any other settings with regard to the OV1 element.

3.16. Limitation of motor starting time Element The CMP1-A41D1 Relay incorporates 2 types of numberof-starts limiting element listed in the table below.

Generally, the specification / data sheet of a motor describes how many start-stop cycles the motor is allowed to go through in a given duration of time. This element outputs an operating signal when the motor has exceeded the prescribed number of start-stop cycles. This element, combined with an external sequence (starting sequence), can prevent the motor from repeating start-stop cycles excessively.

Limitation of motor starting time Element (Accumulated-heat Type) (MST1)

Fig. 3-28 shows the internal function blocks of MST1 element.

MST1 Element performs a motor start assessment on the basis of A-phase current. The element counts the number of starts up by one each time it detects a motor start and outputs a deterministic signal after the lapse of time which is calculated from number-of-starts setting value (Str. Times) and operation timer period (Str. Time). Described below are motor start condition, start-complete condition and number-of-starts assessment equation:

Motor start condition Current to the motor has changed from 10% below the motors rated current to 150% over the motors rated current within a period of approximately 60 ms.

Start-complete condition Current to the motor, following the above-mentioned condition, has stayed 125% below the motors rated current for a period of 100 ms.

Number-of-starts assessment equation MST1 operation time = (Number of starts 1) x starting time + 1 second

Example Number of starts (Str. Times) = 4 Starting time (Str. Time) = 10 seconds, MST1 operation time = (4 1) 10 + 1 = 31 seconds.

Also, because cumulated time (starting time x number of starts) is reduced in accordance with a decrease rate setting (Dec. Rate), this element resets itself when it has gone down to a level of cumulated time which permits its restart. Note that MST1 Element is provided with a capability of zero-clearing the number of starts to facilitate the

performance of testing. This capability can be set from the front panel or PC tool. In addition, MST1 Element outputs an operating signal only when its enable/disable setting (MST1 EN) is set for ON. If you do not want to use this element, switch the setting to OFF. This will prevent the unnecessary actuation of the element. In regard to MST1-related setting items, anything else does not have to be set.

Limitation of motor starting time Element (Simple Number-of-starts Type) (MST2) The internal function block diagram shown in Fig. 3-29 explains how the limitation of motor starting time

element (Simple Number-of-starts type) works. MST2 Element acquires the A-phase current to judge the motor starting condition. The element counts the

number of starts up by one each time it detects the motor start condition which is described below and allows a detection output to activate when the number of starts has reached a setting value (Str. Times) within a certain duration of time (one hour) and outputs a deterministic signal after the lapse of one second. Described below is the motor start condition and start-complete condition:

Motor start condition .......... Current to the motor has changed from 10% below the motors rated current to 150% over the motors rated current within a period of approximately 60 ms.

Start-complete condition .... Current to the motor, following the above-mentioned condition, has stayed 125% below the motors rated current for a period of 100 ms.

The setting Str. Times means that one hour is required for internal counter reducing to zero hour after the

motor operates once.

Setting Example 1

Str. Times = 1 time When the motor starting up once a time, the MST2 signal turns ON. And after one (1) hour, the internal counter is reset to zero (0) and 2nd time of the motor starting up is enable.

Setting Example 2

Str. Times = 3 time When the motor starting up 3rd times, the MST2 signal turns ON. And after three (3) hours, the internal counter is reset to zero (0) and 4th time of the motor starting up is enable.

More detail of the MST2 behavior such as the motor acceleration before the internal counter reset to zero, please refer to below Behavior Examples. The setting of reset timer (Rst. Time) means that keeping time of the MST2 element operation signal (MST2)

after the operation. When user assigns this signal to the relay contact output (DO), the DO keeps for the setting time of Rst. Time. Note that MST2 Element is provided with a capability of zero-clearing the number of starts to facilitate the

performance of testing. This capability can be set from the front panel or PC tool. In addition, MST2 Element outputs an operating signal only when its enable/disable setting (MST2 EN) is set for ON. If you do not want to use this element, switch the setting to OFF. This will prevent the unnecessary actuation of the element. In regard to MST2-related setting items, anything else does not have to be set.

condition in the VT, a break in cable or the like and thus locking the voltage element. Internal function block diagram shown in Fig. 3-31 explains how VTF Function works. This function outputs a VTF detection signal and outputs a defined VTF signal after the lapse of 20 seconds

if 3-phase OR signal for line UV element (UV-D) is operative, 3-phase OR signal for current change detection element (OCD-D) and ground-fault overcurrent element are inoperative, DI6 is ON, and VTF function enable/disable setting is ON (VTF EN = ON). By connecting the auxiliary a contact of the switchgear (CB or the like) to DI6, an erroneous detection of

VTF is prevented from occurring while the switchgear is open. That is, if a low voltage is detected despite the absence of current changes and the switchgear being in closed state, it is assumed that any accident has not taken place and instead there is something wrong with VT. Thus, an unnecessary actuation can be prevented by locking the voltage element instantaneously.

3.18. TCSV (Trip coil supervision)

The trip coil supervision function is described using the internal block diagram in Fig. 3-33. 1) When CB is in the closed state: (52a closed)

Since the trip coil supervision current flows into the opto-coupler inside the relay through r, the output of the opto-coupler PC-OUT is turned on (signal of PC-OUT = 1). Then, as shown in Fig. 3-31, the alarm signal of trip coil supervision (TCSV) does not operate. Furthermore, since supervision current is about 2 mA to 3 mA, it does not affect the operation of the trip coil.

2) When CB is in the open state: (52b closed)

Since trip coil supervision current flows into the opto-coupler inside the relay through the resistor R which is outside the relay and is connected to 52b, output of the opto-coupler PC-OUT is turned on.

Then, as shown in Fig. 3-31, the alarm signal of trip coil supervision (TCSV) does not operate.. In the same way, since monitoring current is about 2 mA to 3 mA, it does not affect the operation of the trip coil. A resistance value of about 1 k is recommended for the external resistance R.

3) When the trip contact is in the closed state:

Trip current flows, and the CB operates. At this time, the output of opto-coupler PC-OUT is turned off. However, since duration of signal operation is 1 sec or less and there is the preset on-delay timer for alarm output, the alarm signal of trip coil supervision (TCSV) does not operate.

4) When T.C. circuit fails:

Because the trip coil supervision current does not flow, output PC-OUT of the photo-coupler inside the relay is turned off, and the alarm signal of trip coil supervision (TCSV) operates after the preset time of the operation timer (Ope. Time) has passed.

3.19. Supervision of zero-sequence voltage

This protection relay monitors zero-sequence voltage in order to detect the voltage input circuit failure.

The supervision of zero-sequence voltage element is described by means of the internal function blocks shown in Fig. 3-34.

When the voltage amplitude of VA + VB + VC 3xV0 exceeds the operating value (10 V), the alarm signal issues after the preset time of the operation timer (Ope. Time) has passed.

A setting V0 SEL is provided in order to select whether the zero-sequence voltage V0 in the arithmetic expression is derived by [(VA+VB+VC)/3], or whether it is taken directly taken from the VN(VG) terminal.

Note that, due to characteristics of the arithmetic expression, this monitoring does not correctly function

when the voltage taken into this equipment is set to the line voltage and in this case, it shall be set Use/Non-use 3PBV EN = OFF..

8. Test

Although all necessary functional tests are implemented for this relay before shipment from the factory, it is recommendable to perform the tests with reference to the following items, before use.

8.1. Visual inspection Perform the visual inspection check with reference to the following items.

Inspection item Contents of inspection

Unit (working part)

(1) No deformation (2) Operational check of the operation key switches (3) Neither discoloration nor deformation of the front

name plate (4) No damage at the terminal connectors

Case No damage including the terminal connectors

Others No foreign substances, such as dust, iron pieces, etc.

180 JEP0-IL9498 C

8.2. Characteristic test

Notes related to the tests

(1) Recommended test condition

Regarding the ambient conditions, following conditions shall be complied with, as far as possible. If the test is performed at the condition which is significantly different from the next condition, the correct test results may not be obtained.

Ambient temperature: 20C 10C

Rated frequency: 1%

Waveform (AC): Distortion factor 2% or less

Control voltage: Rated voltage 2%

(2) Functional control points

Refer to Chapter 6. The functional control point (standard point) of each relays element shall be checked by the relay alone. Therefore, when the combined test with external devices such as VT, EVT, etc. is performed, it shall be considered the error factor of external devices. Furthermore, if user-defined control point is specified (e.g. accracy of relay characteristic is controlled at service conditions), execute the test at the manufacturer-defined control point (mentioned in Section 6.1) before in-service operation and then check accuracy of the relay. After that, execute the test at the user-defined control point, and set this data to the subsequent standards.

(3) Setting change

Refer to 4.3.4.1 for the setting change.

(4) Judgment of operation

Basically, the measurement of the operating value, operating time, etc. shall be done by open/close of the output relay contact of each element.

(5) Communication card

Regardless of equipping or not of the communication card, application of test voltage to the serial communication circuit shall be avoided, at the withstand voltage test and the lightning impulse test.
