Preamble : In order to supply power from generating end to receiving end several equipments are connected in to the system. In order to protect the equipments and components against various operating conditions and over voltages protective devices are required to be installed in the system. Topics specified in this subject deal with various types of protective equipments and their working principle including limitations etc. Electromagnetic Protection Relay connection — Balanced beam type attracted armature relay — induction disc and induction cup relays—Torque equation — Relays classification—Instantaneous— DMT and IDMT types— Applications of relays: Over current and under voltage relays— Directional relays— Differential relays and percentage differential relays— Universal torque equation— Distance relays: Impedance— Reactance— Mho and offset mho relays— Characteristics of distance relays and comparison. Generator Protection Protection of generators against stator faults— Rotor faults and abnormal conditions— restricted earth fault and inter turn fault protection— Numerical examples.

A new chapter on Microprocessor Applications to Protection has been added. Protection of generators against Stator faults, Rotor faults, and Abnormal Conditions. A relay is automatic device which senses an abnormal condition of electrical circuit and closes its contacts. Testing and maintenance of protective gear, Protection against surge-surge absorber, Surge- … Static Relays: Static Relays verses Electromagnetic Relays. Introduction Many electronic designs can take advantage of the improved performance of solid-state relays SSRs relative to that of electro-mechanical relays EMRs that perform the same circuit function. Introduction of static relays began in the early 's.

Function of protective relaying

Mason C. We usually think of an electric power system in terms of its more impressive parts-the big generating stations, transformers, high-voltage lines, etc. While these are some of the basic elements, there are many other necessary and fascinating components. Protective relaying is one of these. Since , the Network Protection and Automation Guide formerly the Protective Relays Application Guide has been the definitive reference textbook for protection engineers and technicians.

General background of the power system and its protection scheme is discussed in this chapter. It also covers the requirements of protection systems and importance of primary and back-up relaying. Consequently, history of protective relays and concepts of adaptive relays are discussed in this chapter.

    The function of protective relaying is to cause the prompt removal from service of any element of a power system when it suffers a short circuit.
