Leakage current relays play a crucial role in ensuring the safety and efficiency of electrical systems. They are designed to detect any abnormal leakage of current, which may otherwise go unnoticed and cause severe electrical hazards. This article delves into the importance, working principle, applications, and benefits of leakage current relays in modern electrical systems.
What is a Leakage Current Relay? A leakage current relay is an electrical protective device used to monitor and detect leakage currents in an electrical system. Leakage current refers to the unintended flow of electric current that escapes the normal circuit path, often due to insulation failures or grounding issues. This can pose serious risks, including electrical shocks, fires, and equipment damage. The leakage current relay helps detect these abnormal currents and promptly shuts down the system, preventing any potential harm or further damage. Working Principle of a Leakage Current Relay
