Overview
The DC resistance test of transformers is a mandatory item for power equipment manufacturers and power generation and supply departments in factory inspection, handover tests, and preventive tests of transformers. It can effectively improve product quality and prevent power accidents. The transformer DC resistance tester is composed of a high-power switching power supply circuit, a precision small-signal measurement circuit, a protection circuit, and a high-speed microcontroller control circuit. It has functions such as instrument self-check, signal measurement, data processing, fast discharge, and result printing.
