KDR-40A DC Resistance Tester - Beijing Kanggaote Instruments and Equipment

Product introduction

Integrating functions of saturable magnetic circuit method, three-phase tests (Yn, Y, △) and degaussing function, this new generation quick-testing device is ideal for measuring DC resistance of large transformers. Boasting a large true color high-resolution LCD screen, dual operation of touch control and jog dial, it’s simple and intuitive to use on site. It’s fast to test with high accuracy and wide measurement range. Once all test wires are connected, all DC resistance test items can be done without readjusting wires.

■ Yn-type, Y-type and △-type winding can be tested in the same way as three phases, and their unbalance rate can be calculated

■ Numerous on-site and off-site test demands of almost all transformers can be met with power supply of maximum output current being 40A, measurement range up to 25kΩ,and the integration of saturable magnetic circuit method and degaussing function

■ It can assist people to judge test data stability and prevent data misreading as resistance change rate within 5s, 15s and 30s can be automatically calculated during tests

■ Numerous protections against misconnection to 380V power,back electromotive force, disconnection, power failure and bad grounding

■ Equipped with a thermal printer, supporting 200 items of data storage locally and mass data storage in USB disks

■ Comfortable and convenient user experience with fresh and simple 7-inch industrial true color screen, supporting dual operation by either full touch control or jog dial
