MIZC-10A Handheld DC Resistance Tester

MIZC-10A Handheld DC Resistance Tester

Product Introduction

The DC resistance of transformers is a necessary measurement item for semi-finished and finished products in transformer manufacturing, factory testing, installation, major repairs, changes to tap changers, handover testing, and preventive testing by power departments. It is possible to check the welding quality of the winding joints and whether there is a turn to turn short circuit in the winding. It can also detect whether the various positions of the voltage tap changer are in good contact, whether the actual position of the tap changer matches the indicated position, whether the lead wire is broken, and whether there are broken wires when multiple wires are wound together.MIZC-10A Handheld DC Resistance TesterAdopting new power technology, it has the characteristics of small size, light weight, high output current, good repeatability, strong anti-interference ability, and complete protection function. The whole machine is controlled by a high-speed microcontroller, with a high degree of automation and automatic discharge and discharge alarm functions. The instrument has high testing accuracy, easy operation, and can achieve rapid measurement of transformer direct resistance.

Other name

Handheld DC resistance tester, handheld DC resistance speed tester, handheld transformer DC resistance tester, handheld transformer winding DC resistance tester
