NAZT Transformer DC Resistance Tester – Electrical Testing Instruments for Transformers

Transformer DC Resistance Tester also named Low Resistance Ohmmeter, It is a necessary testing project for transformer transition, overhauling and changing tap switch, it is also an important detecting project after fault. Transformer DC Resistance Tester is a quick test equipment for testing transformers, generators, motors, lines and other DC resistance.
Transformer DC Resistance Tester is integrated high-precision power supply and DC resistance test in a whole as a new instrument, which not only maintain the original advantage but also greatly reduces the size and weight of the instrument and expands the measurement range. The instrument adopts the high-performance single-chip microcomputer control, simple operation, easy to carry, fast testing speed, high precision, good retest, strong anti-interference capability, automatically complete the judgment of steady flow, data acquisition and processing and display resistance, can accurately complete the measurement of transformer dc resistance, This instrument is the best testing equipment for power plant, power supply enterprises, medium and large-sized power transformer manufacturing industries and enterprises.
According to different level of current, Nanao Electric Wuhan Co., LTD has developed six types of Transformer DC Resistance Tester, they are NAZT-5A, NAZT-10A, NAZT-20A, NAZT-40A, NAZT-50A, NAZT -100A, etc.

NAZTS 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 .
