DC 저항 테스터
A200 transformer DC resistance is the project of semi-finished product, 완제품 공장 테스트, 설치, overhaul, after changing tap-changer, handover test and preventive test of power department in transformer manufacturing. You can check the welding quality of the winding joint and whether the winding is inter-turn short circuit, you can detect whether the various positions of the electro-voltage tap-changer contact is good and whether the actual position of the tap-changer is consistent with the indicated position, whether the lead line is broken, and whether there are broken strands of multiple wires and wound.
In order to meet the needs of rapid measurement of transformer DC resistance, the A200 DC resistance tester developed by our company adopts new power supply technology, which has the characteristics of small size, 가벼운 무게, 큰 출력 전류, 좋은 반복성, strong anti-interference ability and perfect protection function.
The whole machine is controlled by high-speed single chip microcomputer, with high degree of automation, automatic discharge and discharge alarm function. The instrument has the advantages of high measuring precision and simple operation, and can realize the rapid measurement of transformer direct resistance.
