  • Distribution Transformer - an overview | ScienceDirect Topics

    A plant with a 1 MVA distribution transformer is simulated. The MV line is assumed sinusoidal and balanced. The transformer is loaded with some single-phase diode rectifiers (the total load is 170 kW) and a 170 kW three-phase diode rectifier. The three-phase rectifier is located near the transformer with a 50 m, 90 mm 2 copper cable.
