Product Description

   
Three Phase Overcurrent Relay Tester Protection Relay Test Set

 

The Purpose Of Tests

Secondary injection tests are always done prior to primary injection tests. The purpose of secondary injection testing is to prove the correct operation of the protection scheme that is downstream from the inputs to the protection relay(s). Why done prior to primary injection tests? This is because the risks during initial testing to the LV side of the equipment under test are minimized.

Relay Protection Test ltems
 

Type of relay protection	Test items	Recommended test module	remarks
Signal relay	Corresponding test items	DC test Intermediate relay DC test	If the intermediate relay requires AC and DC mixed input, please test it in the "AC / DC test" module. If the rated current of the signal relay is too small, it can be tested by the voltage circuit output of the tester.
Time relay
Intermediate relay
Reclosing relay
Current relay	Corresponding test items	AC test Current voltage Inverse time current relay DC test	The sequence component relay can be tested in the special sequence component module of "AC test". The inverse time relay can also be tested in "inverse time overcurrent".
Over (under) voltage relay
Sequence component relay
Synchronous check (or phase comparison) relay
Inverse time current relay
Differential relay	DC magnetization characteristics	Differential relay Differential test Harmonic test	During the test, please refer to the wiring mode of "differential test" in the manual for correct wiring.
	Harmonic braking characteristics
	Proportional braking characteristics	Differential test Differential relay AC test
Power (direction) relay	Corresponding test items	Power direction AC test	Before testing the power (direction) relay, the wiring type and the general action boundary of the protection should be determined in advance.
Impedance relay
Synchronizing relay	Corresponding test items	Simultaneous test AC test	The UA and UB of the tester are used as the voltage output of the system side and the side to be paralleled respectively in the "synchronization test" module, which can measure the action frequency, action voltage and phase, and carry out automatic quasi synchronization test.
Frequency relay	Corresponding test items	Frequency test	It can be used to test the slip and closing frequency.
