The transformer DC resistance tester is a new type of instrument designed to measure the DC resistance of large-capacity transformers. It is a high-precision stable current power supply and testing part designed as a whole. The testing process is controlled by a microcomputer and automatically completes stable current judgment, data collection, data processing, resistance display and printing.
