MIBZC-3S Three Circuit Transformer DC Resistance Tester

MIBZC-3S Three Circuit Transformer DC Resistance Tester

Product Introduction

The DC resistance of transformers is a necessary measurement item for semi-finished and finished products in transformer manufacturing, factory testing, installation, handover testing, and preventive testing by the power department,MIBZC-3S Three Circuit Transformer DC Resistance TesterIt can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of transformer coils, as well as hidden dangers that exist after operation.

Other name

Three channel transformer DC resistance tester, DC resistance speed tester, transformer DC resistance tester

Product features

1When testing windings with neutral points led out by star connections, the instrument can adopt a three-phase simultaneous measurement method for testingA0TheB0TheC0The DC resistance of the phase greatly saves testing time;
2Display and print all test data of the high, medium, and low voltage windings of the transformer, and automatically calculate the three-phase unbalance rate;
3Equipped with comprehensive back electromotive force protection function;
4Equipped with automatic discharge and discharge indication functions, reducing misoperation and ensuring equipment and personnel safety;
5The instrument canStore test data500Groups can also use USB drives to store data;
6The instrument adopts5.7An ultra large LCD display that can print test results at any time;
7The instrument has the characteristics of wide temperature range, high accuracy, shock resistance, anti-interference, and easy portability.
