Philosophy of relaying

PHILOSOPHICALLY the electric power system exists to serve certain human needs and it must serve them better and more economically than they could be served by other methods or it would not be able to continue to exist or to grow. The rendering of service of the required degree of excellence, within economic limitations, is not an inherent attribute of the electric power system but is the result of sustained and carefully co-ordinated effort on the part of all concerned in the rendering of the service, including 1. Precautions taken in the design of equipment to make it trouble free and reliable. 2. Precautions taken in system layout and connections to enable service to be rendered continuously under adverse as well as under favorable conditions. 3. Precautions taken in the operation and maintenance of the system to avoid unnecessary interruptions to service.
