Product Description

Three phase  Transformer DC Resistance Meter

 

1.Brief introduction

This DC resistance tester is designed for measuring dc resistance of large capacity 3-phase power transformer. It can test three phase winding of transformer at the same time .

For on-load regulating transformer, tap switch can be directly adjusted without discharging, and the measuring time is one third of the traditional single-phase measurement, which can greatly reduce the working time and labor intensity. It adopts large LCD display, English graphic interface, clear and intuitive, easy to operate.

It is also equipped with a panel printer and a large capacity non-volatile memory, which can conveniently store and print the measurement results.The test data is stable, fast and repeatable, which is the best choice for field measurement of dc resistance of transformer.
