HVDC Transmission - DOKUMEN.PUB pulse is transmitted through the pulse transformer secondaries to all the SCRs simultaneously. The insulation between the windings of the pulse transformer must be able to support at least the peak of the supply voltage. As the system voltage becomes higher, the design of pulse transformer will become very difficult. Fig. 2.13
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.
