Three-channel Transformer DC Resistance Tester

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 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.

Product Features:

 

1 On star connection with neutral point leads winding test, the instrument can simultaneously measure three-phase A0, B0, C0 phase DC resistance, saving test time;
2 Display, print all the tested data of transformer high voltage winding, and automatical calculates the three-phase unbalanced ratio;
3 With perfect counter emf protective function;
4 With automatic discharge and discharge indicator function, to reduce the misuse, ensure the equipment and personnel safety;
5 The instrument can store 500 groups of tested data permanently, also can use USB flash drives to store data;
6 The instrument uses 5.7 -inch large LCD, can print the test results at any time;
7 The instrument can suitable for wide range of temperature, with high precision, shock-proof and anti-jamming function, is portable and convenient.
