    Turns Ratio Testing. The transformer turns ratio test is used to make sure that the ratio between the windings of the primary and secondary coils follow the proper specifications. Insulation Resistance Testing. Commonly known as the Megger test, insulation resistance testing measures the quality of insulation within the transformer. Power Factor Testing. The power factor test determines the power loss of the transformerinsulation system by measuring the power angle between an applied AC voltage and the resultant current. Resistance Testing. Resistance testing is conducted several hours after a transformer has stopped conducting current when it reaches the same temperature as its surroundings.
