XZH TEST single phase three phase 20A transformer DC winding
resistance tester
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.
