Cable joint breakdown accidents have occurred frequently in recent years and have gradually become an important concern of the power maintenance department.

Relay protection according to different functions

The various protective functions available on a given relay are denoted by standard. For example, a relay including function 51 would be a timed overcurrent protective relay. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function (time-based, current, voltage). Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. It functions as a watchdog by constantly surveying multiple system components including voltage, current, frequency, and phase angle. A protective relay definition is; a switchgear device used to detect faults & begin the circuit breaker operation to separate the faulty element of the system.
