Substation and its Components
Sub-Station It is a conversion point between transmission-level voltages (such as 138 kV) and distribution level voltages (such as 11 kV). A substation has one or more step down transformers and serves a regional area such as part of a city or neighborhood. They are connected to each other by a transmission ring circuit. Equipment and its function 1). Lightening Arrestor This is the first component in an electrical substation, and the principle capacity of these segments is to shield the segments of the substation from passing high voltage just as stops the amplitude and duration of the flow of current . The light arrestor segments are associated among the earth just as a line which mean parallel to the parts under resistance at the electrical substation. Bushings and Lightning Arrestor These parts divert the flow of current to the ground and hence secure the framework's conductor just as protection from damage. Th Lightning Arrestor does not let the
