A voltage relay is an electronic control device, it has a control system (also known as an input loop) and a controlled system (also known as an output loop), usually used in automatic control circuits, it actually uses a smaller currentAn "automatic switch" to control larger currents.Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.Mainly used in relay protection devices of generators, transformers and transmission lines, as a starting element for overvoltage protection or low voltage blocking.

It is divided into over-voltage relay and under-voltage relay.The former acts when the voltage value increases and reaches the set value, and then is in a post-acting state; the latter acts when the voltage value decreases and reaches the set value, and then is in a release state.Voltage relays include electromagnetic type and transistor type.
