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.

Types of Electrical Protection Relays or Protective Relays

Types of protection relays are mainly based on their characteristic, logic, on actuating parameter and operation mechanism. Protective relays can be categorized based on their operating

Relay Classification in Power System Protection

There are various types of Relay Classification in Power System Protection. Normally the actuating quantity is an electrical signal, although sometimes the actuating quantity may be pressure or

Protective Relay

Electrical protection is provided by a protection relay. The protection relay greatly minimizes or completely prevents equipment damage by identifying issues early on.
