Protective Relaying

Protective Relaying is a vital part of any electric power system: quite unnecessary during normal operation but very important during trouble, faults and abnormal disturbances. Protective Relaying can be considered a vertical specialty with a horizontal vantage point: thus, while specialized, it is involved with and requires knowledge of all of the equipment required in the generation, transmission, distribution and utilization of electrical power.


To provide the fundamental knowledge and field application of protective relay in electric power system which is vital in electrical power system.
