In modern electrical systems, safety is a primary concern, and protecting people and equipment from electrical faults is paramount. One of the essential protective devices used in many industries and residential setups is the Leakage Current Relay. This device plays a vital role in safeguarding both electrical installations and personnel from the potentially harmful effects of leakage currents. In this article, we will explore the workings, applications, advantages, and importance of the Leakage Current Relay in contemporary electrical systems.

What is a Leakage Current Relay? A Leakage Current Relay is a safety device designed to detect and respond to leakage currents in electrical circuits. These currents typically flow to the ground or unintended paths, potentially causing electrical shocks, equipment damage, or even fires. The relay monitors the circuit for abnormal current flow, and if a leakage current surpasses a pre-set threshold, the relay immediately activates to disconnect the circuit. By doing so, it prevents further harm and provides protection to both people and equipment. How Does a Leakage Current Relay Work?
