The invention relates to an automatic test
system for
transformer relay protection equipment. The
system comprises a clamp, a
relay protection instrument, a switch and a host computer, the clamp is provided with a connection port which is connected to the to-be-tested equipment, the to-be-tested equipment is connected with one end of the
relay protection instrument through the connection port, theother end of the relay protection instrument is connected with one end of the switch, and the other end of the switch is connected with the host computer. The host computer sends a test instruction to the relay protection instrument through the switch; the relay protection instrument determines the output analog quantity of the tested equipment according to the test instruction; and the tested equipment acts based on the output analog quantity, and feeds back the generated
test data k to the relay protection instrument through the connection port, the relay protection instrument generates a corresponding test result according to the
test data and feeds the test result back to the host computer through the switch, and the host computer judges the test result and generates a corresponding
test report. Automatic execution of different test items can be realized, the test result is judged, and the working efficiency of the test process is improved.
