Winding Resistance Tester for Power Transformers




Winding resistance test is an important parameter in the maintenance of power transformers or energy continuity. The winding resistance must be known in order to calculate the losses, winding temperature and efficiency. Transformers’ vibrations, overloads and large temperature changes affect the winding resistors. WRT-10 ™ has superior performance in measuring winding resistances of transformers.
