Product introduction

NAZT-S Three-channel Transformer DC resistance tester (hereinafter referred to as direct resistance meter) is the latest generation product of transformer DC resistance measurement, used for measuring large-capacity transformer three-phase winding DC resistance. Three-phase transformer winding DC resistance can be tested simultaneously . For loaded tap changer, it’s no need to discharge, just to regulate the tap directly. The measuring time is one-third of traditional single-phase measuring time, can reduce the working hours and labor intensity greatly Direct resistance tester using a large-screen LCD display, full English graphical interface, clear and intuitive, is very simple to operate. And equipped with a large-capacity printer panel and a nonvolatile memory, can storage and print easily. The testing data is stable, fast and reproducible, is the best choice for on-site transformer DC resistance measuring .
