Estudo teórico de ensaio de tensão em curto-circuito em transformadores de 750kVA – 15kV

Abstract

This work aims at submitting to a voltage transformer three-phase short circuit, and in so doing increases the tension gradually up to the rated current. Therefore, this test simulates transformer at full load. Since the objectives of the test transformer short circuit they are; Determining the losses in the copper (in the conductors which compose the coils), and determine the impedance, ohmic resistance and reactance of the winding.
