step S8: the analog quantity output automatic meter reading is carried out, an analog quantity output control instruction is issued to the relay protection device to be tested through an automatic test background system, and meanwhile, the measurement data of a direct current analog quantity detection module of the whole relay protection device test tool are read, so that the analog quantity output automatic meter reading of the relay protection device to be tested is completed;
step S9: after the test task is completed, automatically displaying a test result through the automatic test background system, automatically writing each item of test data and the test result into a test report, and storing the test report into a computer of the automatic test background system;
step S10: closing a power switch of the relay protection device complete machine test tool to be the relay to be tested
The electric protection device is powered off, another relay protection device to be tested is replaced and powered on, the steps S2 to S9 are repeated,
so as to finish the test of the other relay protection device to be tested.
