Abstract: The fault free operation of a power transformer is a factor of major economic importance and safety in power supply utilities.  In manual method, lot of time is required to test any type of transformer and risk involved is higher. In this paper, various intelligence techniques are used to test transformer. Such techniques used are Voltage Ratio test, Magnetic Balance test, Winding Resistance test, Polarisation Index test, etc. This study focuses on the temperature of transformer winding, voltage ratio across HV-LV, asymmetrical flux distribution in the core, insulation resistance of paper and oil insulation.

 
Keywords: Voltage Ratio test, Magnetic Balance test, Winding Resistance test, Insulation Resistance test, Short-Circuit Test, Magnetizing Current test
