Overview
The UHV-S20A circuit DC resistance tester can simultaneously test the DC resistance of the YN three-phase winding of transformers. It has * protection function and a LCD full Chinese menu with simple and intuitive operation
Product Details
The three-phase DC resistance tester (hereinafter referred to as DC resistance tester) is a generation of product for measuring the DC resistance of transformers. It is optimized for measuring the DC resistance of large capacity transformer three-phase windings. Simultaneously test the DC resistance of the three-phase winding of the transformer. For on load tap changers, there is no need for discharge, and the tap changer can be directly adjusted. The measurement time is one-third of traditional single-phase measurement, which can greatly shorten the working time and labor intensity. The direct resistance meter adopts a large screen LCD display with a fully Chinese graphical interface, which is clear and intuitive, and the operation is very simple.UHV-S20A Loop DC Resistance TesterEquipped with a panel printer and large capacity non-volatile memory, it can conveniently store and print measurement results. The test data is stable, fast, and has good repeatability, making it a high-quality choice for on-site measurement of transformer DC resistance.
