GYKZ-20A Inductive Load DC Resistance Quick Tester
GYKZ-20A Inductive Load DC Resistance Quick Tester
The instrument has large output current and light weight;
It has a complete protection circuit and high reliability;
The vertical case structure is convenient for field operation;
It has discharge alarm sound, clear discharge indication, reducing misoperation and other features. The DC resistance quick tester for transformer windings is an essential test item after transformer handover, overhaul, and tap changer changes. Under normal circumstances, using traditional methods (bridge method and voltage drop method) to measure the DC resistance of transformer windings and high-power inductive equipment is a time-consuming and labor-intensive task. To change this situation, shorten measurement time, and reduce the workload of test personnel, our company has developed a DC resistance tester. It adopts brand-new power supply technology and has the characteristics of rapid measurement, compact size, convenient use, and high measurement accuracy. It is an ideal device for measuring the DC resistance of transformer windings and high-power inductive equipment.
