Product introduction

NRZDC-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 Chinese 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 .

Alternative name
DC resistance rapid tester, transformer DC resistance tester, transformer winding DC resistance tester, transformer direct resistance rapid tester, transformer direct resistance rapid tester, inductive loaded DC resistance tester, inductive loaded DC Resistance rapid tester, inductive loaded DC resistance tester, three circuit transformer DC resistance tester, three circuit transformer tester
The Characteristics of the products
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 .
