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 high-power switching power supply circuits, precision small-signal measurement circuits, protection circuits, and high-speed microcontroller control circuits. It has functions such as instrument self-check, signal measurement, data processing, fast discharge, and result printing.
