NRZV Series DC Hipot Test Set for Water Cooled Generator

NRZV Series DC Hipot Test Set for Water Cooled Generator is used for testing DC voltage and DC leakage current of water-cooled generator and other electrical devices in the situation of water through which completely overcome the problems of long blow water time and bottom water hard to dry which easy to cause arcing within the coil. It is specially designed various kinds of interference current compensation loop completely eliminate the influence of stray current and the polarization potential interference of the water collecting pipe during the test and can accurately measure the leakage current of the water-cooled generator winding.
