Transformer Substations - an overview | ScienceDirect Topics a secondary transformer substation is composed of two or three transformers, these transformers may approximately serve for 150–300 customers. When the North American model case is considered, the MV levels are in the range of 4 and 34 kV. The secondary transformers in North America feed LV lines with 120 or 200 V according to load types.Get Price
HVDC Transmission - ScienceDirect· 27.1. Introduction. High-voltage direct current (HVDC) transmission [,, ] is a major user of power electronics technology.HVDC technology first made its mark in the early undersea cable interconnections of Gotland (1954) and Sardinia (1967) and then in long-distance transmission with the Pacific Intertie (1970) and Nelson River (1973) schemes using mercury-arc valves.Get Price
