NDZRC-10A Transformer DC Resistance Tester (with Battery)

Product Introduction

       DC resistance of transformers is a mandatory test item during the manufacturing process, factory acceptance tests, installation, commissioning tests, and preventive maintenance tests conducted by power departments. It effectively identifies manufacturing defects such as material selection, welding issues, loose connections, missing strands, broken wires in transformer windings, as well as problems that arise during operation.

       The Transformer DC Resistance Tester is an innovative product equipped with a high-capacity lithium battery. It is compact and portable, making it easy to carry. It is suitable not only for measuring inductive test objects such as transformers, mutual inductors, and reactors, but also for resistive test objects like copper busbars, wires, and switch contacts. The instrument offers fast testing speed and high accuracy.
