发明名称 PROTECTIVE RELAY, AND TEST METHOD AND TEST CABLE THEREFOR
摘要 PROBLEM TO BE SOLVED: To provide a protective relay that allows the manufacturing cost to be reduced, and a test method and test cable therefor. SOLUTION: When testing protective properties, the control equipment side connector 42 of the control cable 7 is disconnected from the control equipment side connector 31 of the protective relay 65 the switch side connector 61 and the control equipment side test connector 62 are connected to the two connectors 42 and 31, respectively. This allows a ground fault property test to be conducted on the switch 3 and the protective relay 6 using installed connectors 21, 31 and the control cable 7. Thus, in contrast to prior art, there is no need to provide in advance a cable lead-out connector on the control cable 7 connecting the switch 3 and the protective relay 6, thereby reducing the manufacturing cost of the protective relay 6.
