UHV Converter Stations and the Main Electrical Equipment ...· A converter station mainly comprises converters and DC and AC switchyards, and the converter mainly consists of a converter transformer and a converter valve. The DC switchyard accommodates smoothing reactors, DC filters, DC measuring devices, arresters, surge capacitors, coupling capacitors, switchgears, etc.
TRANSMISSION AND DISTRIBUTION Fundamental research in ...· PDF fileTRANSMISSION AND DISTRIBUTION The electrical insulation of a converter transformer differs from that of a regular power transformer since it has to withstand combined AC and DC stresses. Where the material parameter determining the AC field distribution is the permittivity, the DC field distribution is determined by the resistivity.
