Guide Protective relay
OverviewRelays by functionsOperation principlesTypes according to constructionPower source
The various protective functions available on a given relay are denoted by standard ANSI device numbers. For example, a relay including function 51 would be a timed overcurrent protective relay. An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. It is of two types: instantaneous over current (IOC) relay and definite time overcurrent (DTOC) relay.
Guide Differential (87) Current Protection
The concept of protection zones is a very important one in protective relaying, and finds application well beyond differential current (87) systems. It is closely related to the concept of selectivity, which

59 - Overvoltage Function The overvoltage relay triggers a trip signal when the voltage exceeds the set threshold, protecting equipment from potential damage due to high voltage conditions.
Guide Understanding Protective Relays in Electrical Power Systems -
When a fault, such as an overcurrent, undervoltage, or short circuit, is detected, the relay triggers the circuit breaker to isolate the affected area. These devices operate automatically, ensuring minimal
