Portable Transformer Impedance Test Set Short Circuit Impedance Tester

Short Description:


It tests the short-circuit impedance (%) of power voltage on site and compares it with the value indicated on the nameplate or the factory default to find out any defects including but not limited to winding displacement or deformation due to currents from major failure during transformation, installation or operation following the delivery test.
