Question

A three phase Y-Delta transformer is rated 225 kV: 24 kV, 500 MVA and has a single phase equivalent series reactance of 0.06 Ohm referred to its low voltage terminal. The transformer is connected to a load of 375 MVA at 0.8 leading power factor and 20 kV voltage (line) on the low voltage side. The transformer is supplied from a feeder whose impedance is 0.2+j2 Ohm connected to its high voltage terminals. Calculate: Line voltage at the primary side of the transformer The line to line voltage at the sending end of the feeder

Explanation / Answer

2A-2M Copper Tube Terminal Lugs area unit designed for top voltage applications up to 33kV. factory-made from high purity copper tube, toughened and tin-plated. The extended barrel enhances electrical and mechanical performance. The absence of Associate in Nursing review hole prevents wet entry into the crimped joint. that includes Associate in Nursing extended palm with 2 fixing holes at forty four.5mm centres.
