Home / Relay protection devices are used to protect against current surges

What are Protective Relays, or Protection Relays? Protective relays are used in industrial power generation and supply systems to open and isolate branch circuits in the case of excessive current. A surge protector, spike suppressor, surge suppressor, surge diverter,surge protection device (SPD), transient voltage suppressor (TVS), or transient voltage surge suppressor (TVSS) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from. In essence, it surrounds the devices and the electrical supply, acting as a shield. It functions as a watchdog by constantly surveying multiple system components including voltage, current, frequency, and phase angle.
