Description

[0002] A relay, also known as an electric relay, is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. When using a relay, it is necessary to perform a withstand voltage test on the relay's coil, contacts, and disconnection points. Usually, the staff holds a probe connected to a high-voltage tester for testing. Due to the large number of relays in nuclear power plants, manual testing is not convenient and inefficient.
