A Power Substation is specifically designed for transforming voltage from high to low and for performing other integral functions. Thus, it is considered as an integral part of any electrical transmission, generation, and distribution system. It can also be called as the medium that connects users or consumers and generating system. Power Substation consists of transformers, which are used for changing voltage levels between high transmission voltages and low transmission voltages. Further, it is developed under the strict observation of industry experts, who perform various tests on its components as per industry laid norms.
