Introduction to Protective Relaying | Electric Power Measurement

What are Protective Relays, or Protection Relays? Protective relays are used in industrial power generation and supply systems to open and isolate branch circuits in the case of excessive current. They are activated by means which are not dependent on a

What are the principles of protective relaying?

As the principles of protective relaying are developed in this book, the reader will perceive that the entire subject is governed by these general requirements: correct diagnosis of trouble, quick-ness of response and minimum disturbance to the power system.

What are protective relays & control functions?

For our purposes, we may arbitrarily define all functions which lead to operation of power switches or circuit breakers to be the tasks of protective relays, while all actions which change the operating state (voltages, currents, power flows) of the power system without changing its structure to be the domain of control functions.

What are some good books about protective relays?

Mason, C.R. (1956) The Art and Science of Protective Relaying, John Wiley & Sons, Inc., New York. Westinghouse (1976) Applied Protective Relaying, Westinghouse Electric Corporation, Newark, NJ. IEEE (1986) IEEE Recommended Practices for Protection and Coordination of Industrial and Commercial Power Systems (IEEE Buff Book), ANSI/IEEE STD 242-1986.

What is a power factor relay?

For such a system a power factor relay is used.3 The combination of motors, transformers and other electrically driven devices that form an auxiliary system for a power plant presents a protection problem that is, in effect, a microcosm of power system relaying and deserves special mention.

What is a relay in Electrical Engineering?

Relaying is the branch of electric power engineering concerned with the principles of design and operation of equipment (called ‘relays’ or ‘protective relays’) that detects abnormal power system conditions, and initiates corrective action as quickly as possible in order to return the power system to its normal state.

What is adaptive relaying?

Adaptive relaying is a concept that recognizes that relays that protect a power network may need to change their characteristics to suit the prevailing power system conditions. Normally, a protective system responds to faults or abnormal events in a fixed, predetermined manner that is embodied in the characteristics of the relays.
