It receives electrical power from generating station via incoming transmission lines and delivers electrical power via the outgoing transmission lines. Substations are integral parts of a power system and form important links between the generating stations, transmission systems, distribution system and the load points. In every electrical substation, there are various indoor and outdoor equipment's. Each equipment has certain functional requirements. The choice of equipment depends on technical considerations, rated voltage, rated MVA, and the type of substation. Function of substation equipment : Outdoor Equipment's The following are the various EHV outdoor equipment's and their functions are here under. Power Transformer: It is used to step-up or step-down a.c voltages and to transfer ele...
