This comparison summarize characteristics of all protection relay types described in previously published technical articles:
The numbers and acronyms provide identification for a variety of relays that monitor parameters like voltage, current, power, frequency, temperature and other
In the design of electrical power systems, the ANSI Standard Device Numbers (ANSI /IEEE Standard C37.2) denote what features a protective device supports (such as a relay or circuit breaker).
The special equipment adopted to detect such possible faults is referred to as ''Protective equipment or a protective relay'' and the system that uses such equipment is termed a ''Protection system''. protective
