Portable Single Three Phase 20A Transformer DC Winding Resistance Meter

Portable single three phase 20A transformer DC winding resistance meter

Description

For the power system, the transformer is the core equipment in the system, so the long-term and reliable operation of the transformer is related to the stability and reliability of the entire system.

The DC resistance of the transformer is a must-test item for semi-finished products, finished products factory testing, installation, handover testing and preventive testing of the power department in transformer manufacturing. It can effectively detect the material selection, welding, loose connection parts, missing strands, broken wires, etc. of the transformer coil. Defects and hidden dangers after operation. In order to meet the need for rapid measurement of transformer DC resistance, our company used its own technical advantages to develop a transformer DC resistance tester. This instrument is a new generation of fast tester that integrates three-phase test (Yn, Y, △) and demagnetization function. It is an ideal device for measuring the DC resistance of large power transformers. The screen adopts true color high-resolution industrial display screen, full touch operation, Chinese menu prompt function, simple and intuitive operation, fast test speed, high accuracy and wide range.
