Overview
The transformer winding DC resistance tester is a test item for transformers after handover, major repairs, and changes to the tap changer. Under normal circumstances, measuring the DC resistance of transformer windings and high-power inductive devices using traditional methods such as bridge method and voltage drop method is a time-consuming and labor-intensive task. In order to change this situation, shorten measurement time, and reduce the workload of testers, UHV has developed a DC resistance rapid tester. The DC resistance speedometer adopts a new power supply technology, which has the characteristics of stable performance, fast measurement, small size, easy use, high measurement accuracy, and good data repeatability.

Transformer winding DC resistance testerIt is a test item for transformers after handover, major repairs, and changes to tap changers. Under normal circumstances, measuring the DC resistance of transformer windings and high-power inductive devices using traditional methods such as bridge method and voltage drop method is a time-consuming and labor-intensive task. In order to change this situation, shorten measurement time, and reduce the workload of testers, UHV has developed a DC resistance rapid tester (hereinafter referred to as the DC resistance tester). The DC resistance speedometer adopts a new power supply technology, which has the characteristics of stable performance, fast measurement, small size, easy 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.
Transformer winding DC resistance testerMeets the requirements of DL/T845.3-2004 and national standards GB6587-86 "General Principles for Environmental Testing of Electronic Measuring Instruments" and GB6593-86 "Quality Verification Rules for Electronic Instruments".
