Electrical equipment is a general term for equipment such as generators, transformers, power lines, and circuit breakers in power systems. The important role played by electric power in our life and production is not ignored, brings great convenience to our life, and becomes an important energy source in our production and life. The most critical factor in a power plant that allows for the proper operation and delivery of electricity is the electrical equipment.

A relay is an electric control device that generates a predetermined step change in a controlled amount in an electric output circuit when a change in an input amount (excitation amount) meets a predetermined requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is usually applied to automatic control circuit, and it is an "automatic switch" which uses small current to control large current operation, so that it can play the role of automatic regulation, safety protection and switching circuit in the circuit.
