HZ-3120A Digital Fast Transformer DC Resistance Tester 20A
Introduction
DC resistance measurement is a key test item for transformers, covering semi-finished and finished product inspection, installation and commissioning, as well as preventive tests in the power industry. It can effectively detect defects and potential hazards arising from manufacturing and operation, such as improper coil material selection, welding issues, loose connections, short circuits, and open circuits.
To meet the demand for rapid measurement of transformer DC resistance, a new generation of CT Series DC Resistance Tester has been developed.
The instrument adopts the new program-controlled linear constant current source technology, with large output current, current gear, small volume, light weight, etc.
