Is relay protection operated from the electrical box Why
Once a protection relay detects a fault, it will operate automatically and will close down the breaker's trip circuit. This way the faulty circuit will be disconnected from the system and the circuit breaker will be open. It has a set of input terminals for one or more control signals, and a set of operating contact terminals. Engineering use: Relays are used on feeders, transformers, buses, motors, generators, and transmission lines to protect equipment and improve system. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.

The Role of Electrical Control Relay Protection Systems
Protective relays and devices have been developed over 100 years ago to provide “last line” 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. Engineering use: Relays are used in control panels, motor circuits, PLC interfaces, alarms, breaker trip circuits, and power system protection schemes. In other words, the prime function of protective relays is the timely and.

Relay protection overcurrent return value
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. 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.
