10A,20A,40A.50A transformer DC winding resistance tester portable dc wind resistance meter
I. Summary
Transformer DC Winding Resistance tester is a transformer manufacturing of semi-finished products, finished products testing, installation, commissioning test and power sector preventive test will measure project, can effectively find the transformer coil material selection, welding, loose connection parts, short, break the blemish such as manufacturing and running after the existence of hidden dangers.In order to meet the needs of transformer dc resistance rapid measurement, it has developed a new generation of CT series dc resistance tester.
The instrument adopts the new program-controlled linear constant current source technology, with large output current, current gear, small volume, light weight, etc.
The Transformer DC Winding Resistance tester is controlled by a single-chip microcomputer, automatic complete self-checking, data processing, display, save, print, and other functions, with sophisticated electronic measuring technology, makes the instrument is of high precision and wide measuring range, easy operation, can realize the sensibility of transformer and voltage transformer resistance rapid measurement.
