Distribution Substations~avsergue/EET3390/Lectures/CHAPTER6.pdf· PDF fileDistribution substation A distribution substation transfers power from the transmission system to the distribution system of an area. The input for a distribution substation is typically at least two transmission or subtransmission lines. Distribution voltages are typically medium voltage, between 2.4 and 33 kV depending on the size of the area served and the practices of the local utility.
Substation: Functions and Purpose - GlobeCore on the design there are indoor and outdoor substations. Outdoor substation equipment is located outdoors. Indoor substations equipment is reliably protected from adverse weather conditions indoors. Substations for voltage of 6-10 kV are located in cities, towns and villages. They are serviced by mobile service crews.
