  • Relay protection that responds to electrical quantities

    Relay protection that responds to electrical quantities

    Protective relays form the backbone of modern power system protection, ensuring both equipment safety and system reliability. Its primary function is to detect abnormal conditions, such as. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. While this is bad, It's not a.
