Wuhan GDMK Electric Co., Ltd.

Product description:

Multifunctional transformer test bench is a new generation of calibrating device, faster and more accurate. We dedicately develop it to meet the demand of modern calibration. It is made up of an HGQA-C Transformer Calibrator, a current load case, a special test standard for CT and so on. Inheriting the oringinal the features, it is remarkably improved. With flexible match with more load cases and transformers, it performs excellently in quick test and quick point location during CT test.
