Open and Short Circuit Test on a Single Phase Transformer

OBJECTIVES:

The open-circuit test is used to determine the impedance in the excitation branch of a real
transformer. This test only measures the combined iron losses consisting of the hysteresis
loss and the eddy current loss.

The purpose of a short-circuit test is to determine the series branch parameters of the
equivalent circuit of a real transformer. This test measures only the full load copper loss

Required Modules:

 VARIABLE SINGLE PHASE
 AC SUPPLY
 VOLTMETER
 AMMETER
 WATTMETER
 SINGLE PHASE TRANSFORMER
