Relay protection type | Test items | Suggested test module | Remark | ||
Line protection | Multistage | ||||
Over /(under) voltage | |||||
Sequence component voltage and current | |||||
Frequency device | |||||
Power direction protection | |||||
Reclosing and conversion fault | Corresponding test item | Complete set test, line protection, state series, 6-35KV line protection integrated test | It's required to test the synchronization check and no-voltage check and use Ux as the voltage output of connected side while the 1200 tester uses Ua instead of Ux for test. | ||
Distance and zero sequence | Distance and zero sequence fixed value verification | Distance and zero sequence, line protection, complete set test, AC test | Both "distance and zero sequence" and "line protection" can automatically simultaneously test the distance and zero sequence fixed value of multiple stages, various fault types and various phases. | ||
Impedance characteristics | Impedance characteristics | ||||
Power frequency variation impedance | Fixed value verification | Distance and zero sequence, line protection | 10~15A The fault current should be large enough such as 10-15A (in the case of CT of 5A system) | ||
Overcurrent protection of composite voltage blocking (direction) | Overcurrent, low voltage, negative sequence voltage, angle of sensitivity, etc | AC test, 6-35KV line protection integrated test | The "low voltage" and "negative sequence voltage" under protection will be input from different terminals and the wiring needs to be changed at test | ||
Low cycle, low voltage deloading device | Corresponding test item | Frequency and high and low cycle, 6-35KV line protection integrated test | If other conditions are all met but the device still fails to operate, please confirm whether the device needs current input and switch contact at the same time | ||
Generator protection | Differential protection | Proportion braking characteristics | Differential protection, differential fixed value, AC test | As to generator differential protection, when testing with the "differential protection", it can be seen as power transformer protection with the wiring type as Y/Y and the high and low voltage side balance coefficient as 1 | |
"Differential protection" focuses on curve characteristics search, while "differential fixed value" module focuses on differential fixed value test and the combination of both provides a comprehensive test of differential protection | |||||
Harmonic braking characteristics | Differential protection, differential fixed value, AC test | ||||
Field loss protection | Corresponding test item | AC test | Attention should be paid to the angle of output voltage and current in the test. | ||
Excitation protection | |||||
Overcurrent protection of composite voltage blocking (direction) (reserve) | Corresponding test item | Please refer to the above "line protection" section | Please refer to the above "line protection" section | ||
Other protection | Automatic synchronized device | Corresponding test item | Synchronization test | When the automatic adjustment test is conducted, wiring shall be made according to the manual for each switch input test | |
Bus differential protection | Corresponding test item | AC test | Please refer to the instructions on BP-2B and RCS-915 in "NARI Part Protection" of Appendix 6 | ||
Line differential protection | First determine whether the device forms "self-loop" before test. If so, the protection operating value should be equal to half of its setting value |
