Product Introduction

The DC resistance of transformer is a necessary test item for the factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department in the manufacture of semi-finished products and finished products of transformer. It can check the welding quality of the winding joint and whether the winding has inter turn short circuit. It can detect whether the contact at each position of the voltage tap changer is good, whether the actual position of the tap changer is consistent with the indicated position, whether the outgoing line is broken, and whether there are broken strands of multi strand conductors. The instrument adopts new power supply technology and has the characteristics of small volume, light weight, large output current, good repeatability,strong anti-interference ability and perfect protection function. The whole machine is controlled by high-speed single chip microcomputer with high degree of automation, and has the functions of automatic discharge and discharge alarm. The instrument has high test precision and simple operation, and can realize the rapid measurement of transformer direct resistance.

Functional Characteristics
