Leakage Current Relay (LCR) is an essential protective device widely used in electrical systems to detect and mitigate leakage currents. These devices play a critical role in safeguarding both personnel and equipment from electrical hazards that could arise due to insulation failure or grounding issues. This article explores the functioning, applications, and significance of leakage current relays in modern electrical safety systems.
What is a Leakage Current Relay? A Leakage Current Relay is a type of relay designed to detect abnormal leakage currents in electrical systems. Typically, leakage currents are the unintended flow of electric current from a conductor to the earth or other conductors, which occurs due to poor insulation or other faults. In the event of such leakage, the relay is capable of sensing the leakage current and triggering a protection mechanism to disconnect the faulty circuit, thus preventing potential hazards like electric shock, fire, or equipment damage.
