Induced Voltage Induced Frequency Test Set

Product Description:

Distribution power transformer has large number of turns test possible that to turn might internally short circuit, which is not easily traceable. To detect teh fault, twice voltage is applied to the transformer winding and at twice frequency to maintain the magnetising of the current with in limits. The nodded of the current of the transformer is measured before and after the test. If remain same the winding is O.K. If the nodded is increased, the winding is faulty.
