BZC-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,BZC-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.

Product features

1. When testing windings with neutral point leads in the star connection method, the instrument can adopt a three-phase simultaneous measurement method to test the DC resistance of A0, B0, and C0 phases, greatly saving testing time;
2. Display and print all test data of the high, medium, and low voltage windings of the transformer, and automatically calculate the three-phase unbalance rate;
3BZC-3S Three Circuit Transformer DC Resistance TesterEquipped with reverse electromotive force protection function;
4. Equipped with automatic discharge and discharge indication functions, reducing misoperation and ensuring equipment and personnel safety;
5. The instrument can store 500 sets of test data and can also use a USB drive to store data;
6. The instrument adopts a 5.7-inch ultra large LCD display, which can print test results at any time;
7. The instrument has the characteristics of wide temperature range, high accuracy, shock resistance, anti-interference, and easy portability.
