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. |

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". |

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. |

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. |
