Product Description

Product Description

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

Functional 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 imbalance rate;

3.Equipped with comprehensive back electromotive force protection function;

4.Equipped with automatic discharge and discharge indication functions, reducing misoperation and ensuring the safety of equipment and personnel;

5.The instrument can permanently store 500 sets of test data and can also use USB flash drives to store data;

6.The instrument adopts a 5.7-inch super 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 convenient portability.
