MIBZC-40A Transformer DC Resistance Tester

MIBZC-40A Transformer DC Resistance Tester

Product Introduction

MIBZC-40A Transformer DC Resistance TesterMainly used for measuring DC resistance of large and medium-sized transformers, engines, motors, etc. The instrument is set with multiple current levels to meet various measurement needs.
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. In order to meet the needs of rapid measurement of transformer DC resistance, our company has developed40ADC resistance tester. This instrument adopts a new power technology, which has the characteristics of small size, light weight, large 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.
