Transformer Tester
  • Product Introduction

DC resistance testing for the transformer is an essential item in the ex-factory testing for semi-product or finished product during transformer manufacturing, or in the installation, hand-over and preventive test for power sector. In this way, we can effectively find the manufacturing defects of transformer coils such as material selection, welding, connection parts loose , missing shares, disconnection and the hidden dangers appearing after the transformer operating. To meet the need of quickly measuring transformer DC resistance, we take advantage of our own techniques to develop the ZC-205 Double ChannelTemperature rise DC resistance tester. It adopts new power technology, and the whole machine is controlled by a single-chip microcomputer, thus automatically completing self-checking, data processing, display and printing, etc. It is also with functions of automatic discharge and discharge instructions. The instrument of high precision, simple operation, can realize the rapid measurement of transformer dc resistance.
