Power Testing Level III/DC Resistance Tester
After the transformer is handed over, overhauled, and the tap changer is changed, it is an indispensable test item. In normal circumstances, using traditional methods (bridge method and voltage drop method) to measure transformer windings and the DC resistance of 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 the 40A DC Resistance Rapid Tester (hereinafter referred to as the DC Resistance Tester). It adopts new power supply technology and has the characteristics of stable performance, rapid measurement, compact size, convenient use, high measurement accuracy, and good data repeatability. It is an ideal device for measuring the DC resistance of transformer windings and high-power inductive equipment.
This product complies with the requirements of DL/T845.3-2004, the national standard GB6587 "General Outline for Environmental Testing of Electronic Measuring Instruments," and GB6593 "Rules for Quality Inspection of Electronic Instruments."
