The DC resistance test of the transformer winding is an indispensable test item after the transformer is installed, overhauled and the tap changer is changed. Under normal circumstances, measuring the DC resistance of transformer windings and high-power inductive devices using traditional methods (bridge method and voltage drop method) is a time-consuming and labor-intensive task. In order to change this situation, shorten the measurement time and reduce the workload of testers, a transformer DC resistance tester was developed. It uses a new power supply technology, featuring rapid measurement, compact size, ease of use, and high measurement accuracy. It is an ideal device for measuring the DC resistance of transformer windings and high-power inductive equipment. It can also be used as the DC resistance of the grounding wire.
Transformer DC resistance tester is a new type of instrument designed to measure the DC resistance of large-capacity transformers. It is a high-precision steady-state power supply and test part that is designed as a whole. The test process is controlled by a microcomputer, and the steady flow judgment, data acquisition, data processing, and resistance are automatically completed. Value display and print. The instrument can be completed with one-time power supply for the on-load voltage regulator longitudinal test, fully saving test time, and set up a temperature rise test function for transformer manufacturers. It can achieve fast and accurate measurement of various types of transformers, with simple operation, high precision, Anti-jamming and other features. the test current of Kingrun transformer DC resistance tester reaches 20A, 40A,50A, is the ideal test instrument for power supply units, transformer manufacturing industries and large and medium-sized power companies to ensure safe production and improve product quality.
