Product Details

Quick Details


  The device tests more than one bit transformer device is the company to adapt to the modern transformer check the rapid and accurate development of the characteristics of a new generation of transformer test equipment. The device consists of HGQA-C transformer calibrator, FY98 load current and voltage transformer box, control cabinet, current transformers, special test bench, and several other components. In maintaining the technical characteristics of the original premise, the rapid measurement of the current transformer quickly locate the test points, and the load box, the transformer turns ratio coverage of various aspects has been greatly improved.
