ShanghaiTransformer DC resistance testerCompliant with national standards
It 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, our company has developed a DC resistance rapid tester. It adopts a new power technology, which has the characteristics of fast measurement, compact size, easy use, and high measurement accuracy. 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 the national standards GB6587-86 "General Principles for Environmental Testing of Electronic Measuring Instruments" and GB6593-86 "Quality Verification Rules for Electronic Instruments".
ofTransformer DC resistance testerUsing a 32-bit ARM core as the processing core, the entire machine is controlled to automatically perform functions such as self calibration, current stabilization judgment, data processing, and resistance display. It can measure the DC resistance of various types of transformers and mutual inductors. It greatly facilitates the use of staff.
