Abstract: Transformer is an important component in electric power system. The function of the transformer is to adjust the current and voltage values so that it can be used according to usage needs. In the operation of electric power distribution, the transformer is the heart of transmission and distribution. The transformer is expected to operate optimally, so that the continuity and quality of electrical energy can be maintained. The main objective of testing the transformer is to know the quality of the machine, quality of materials used for manufacturing the machine and also to check its behavior and performance as per the design data. In this paper, various techniques are used to test transformer such as Voltage Ratio test, Winding Resistance test, Polarity and Phasing out test, etc. are presented and the troubleshooting of transformers is also covered briefly.
Keywords: Voltage Ratio test, Winding Resistance test, Polarity and Phasing out test, Insulation Resistance test, Short-Circuit Test, Magnetizing Current test.
