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.

Communication devices in the relay protection room

Let's start with brief description of seven most known and most used communication medias used in power system communications (in terms of protection and automation):.

How to connect protection inputs to relay protection

The objective of relay protection is to quickly isolate a faulty section from both ends so that the rest of the system can function satisfactorily.
