Russell MasonWHAT IS PROTECTIVE RELAYING?We usually think of an electric power system in terms of its more impressive parts–the big generating stations, transformers, highvoltage lines, etc. While these are some of the basic elements, there are many other necessary and fascinating ponents. Protective relaying is one of these.The role of protective relaying in electricpowersystem design and operation is explained by a brief examination of the overall background. There are three aspects of a power system that will serve the purposes of this examination. These aspects are as follows:A. Normal operationB. Prevention of electrical failure.C. Mitigation of the effects of electrical failure.The term “normal operation” assumes no failures of equipment, no mistakes of personnel, nor “acts of God.” It involves the minimum requirements for supplying the existing load and a certain amount of anticipated future load. Some of the considerations are:A. Choice between hydro, steam, or other sources of power.B. Location of generating stations.C. Transmission of power to the load.D. Study of the load characteristics and planning for its future growth.E. MeteringF. Voltage and frequency regulation.G. System operation.H. Normal maintenance.The provisions for normal operation involve the major expense for equipment and operation, but a system designed according to this aspect alone could not possibly meet presentday requirements. Electrical equipment failures would cause intolerable outages. There must be additional provisions to minimize damage to equipment and interruptions to the service when failures occur.Two recourses are open: (1) to incorporate features of design aimed at preventing failures, and (2) to include provisions for mitigating the effects of failure when it occurs. Modern powersystem design employs varying degrees of both recourses, as dictated by the economics of any particular situation. Notable advances continue to be made toward greater reliability. But also, increasingly greater reliance is being placed on electric power. Consequently, even though the probability of failure is decreased, the tolerance of the possible harm to the service is also decreased. But it is futileor at least not economically justifiableto try to prevent failures pletely. Sooner or later the law of diminishing returns makes itself felt. Where this occurs will vary between systems and between parts of a system, but, when this point is reached, further expenditure for failure prevention is discouraged. It is much more profitable, then, to let some failures occur and to provide for mitigating their effects.The type of electrical failure that causes greatest concern is the short circuit, or “fa
