Product Description

Product Description

The DC resistance of transformers is a mandatory test item for semi-finished products,finishedproducts,factory tests,installation,handover tests,and preventive tests by the power department.It effectively identifies manufacturing defects such as poor material selection,loose soldering,connection issues,missing strands,broken wires,and operational hazards.
To meet the need for rapid measurement of transformer DC resistance,our company hasleveraged its technical advantages to develop the Transformer DC Resistance Tester.

Product Features

1. For testing star-connected windings with a neutral pointlead-out,the instrument can measure the resistance of phases A0,B0,and CO simultaneously,saving test time

2. For Yand △-connected windings,the instrument can performautomatic three-phase testing and calculate the three-phaseunbalance rate;

3. The instrument features a magnetization testing method and ademagnetization function;

4. It includes multiple protection features such as back EMFprotection,open circuit protection,and power-off protection;

5. The instrument has a wide measurement range;

6. Features a non-volatile clock and date display;

7. Equipped with a thermal printer for quick,silent printing;

8. Compact and lightweight for easy portability
