Transformer DC resistance tester

The transformer DC resistance tester is a new instrument that integrates a high-precision constant-current power supply and DC resistance measurement. It dramatically reduces the instrument’s volume and weight and extends its measurement range. The instrument is controlled by a high-performance microcontroller, which automatically completes the judgment of steady current, data acquisition and processing, and resistance display, able to quickly and accurately complete the transformer, transformer, generator, motor and line resistance of the rapid measurement, it is an ideal test product for power generation and supply units, transformer manufacturing industry and large and medium-sized power enterprises.

The DC resistance of the transformer is a necessary test item in the factory test, installation, handover test and preventive test of the semi-finished products and finished products in the transformer manufacturing, can effectively find the transformer coil material selection, welding, loose connection parts, Strand, broken and other manufacturing defects and hidden dangers after operation.
