Power transformer as an important electrical equipment, its safe and reliable operation is extremely important for power systems. After the impact of short-circuit current, the transformer winding deformation test is very important. To short-circuit the low-voltage winding side of the transformer and apply a low voltage of the operating frequency (50Hz or 60Hz normally) to the high voltage winding side of the transformer, the short-circuit impedance method measures the short-circuit impedance of the operating frequency.The test result is mainly leakage reactance component, determined by the geometry of the winding. The change of the transformer winding structure will cause changes of the transformer leakage reactance, resulting in transformer short circuit impedance numerical changes. The tester,follow the national power industry standards DLT 1093-2008, and can be used for IEC60076-5-2006. also,the tester can also be used for generator rotor AC impedance test, transformer load and no load loss test..
