The relays represent the most important category of devices in a protection and automatic control instalation. The relays are switching devices equiped with one or more contacts, driven by an electrical signal. Used to switch a high voltage value of the current into a smaller one, the relays are formed by a coil, one or more contacts and a sprin...
