1 ZZC50 Three way Transformer DC Resistance TesterOverview

For the power system, transformers are the core equipment in the system, so the long-term and reliable operation of transformers is related to the stability and reliability of the entire system.

The DC resistance of transformers is a necessary test item for semi-finished and finished products in transformer manufacturing, factory testing, installation, handover testing, and preventive testing by the power department. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of transformer coils, as well as hidden dangers after operation.In order to meet the needs of rapid measurement of DC resistance in transformers, our company has developed using our own technological advantagesA transformer DC resistance tester. This instrument is a setMagnetic assisted testing, three-phase testing（and Y,andDemagnetization functionThe new generation of rapid testing equipment integrated into one isIdeal equipment for measuring the DC resistance of large power transformers.The screen adopts a true color large screen high-resolution LCD display, with touch control and shuttle knob operation, making it convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and can complete all direct resistance test items in one wiring. The testing speed is fast, the accuracy is high, and the range is wide.
