New equivalent circuit model of UHVDC converter transformer winding for surge propagation investigation

New equivalent circuit model of UHVDC converter transformer winding for surge propagation investigation

An accurate computational model of transformer winding for potential distribution analysis under impulse voltage is very important for the design of transformer inter-turn insulation, especially for large capacity transformers such as ultrahigh-voltage DC (UHVDC) converter transformer. Quite a lot o...
