The XHZ1010 DC Resistance Tester is essential for all critical stages of transformer lifecycle testing: from factory checks of semi-finished/finished products, to installation, overhaul, tap changer adjustments, handover, and preventive testing by power sectors. It performs vital diagnostic tasks: assessing winding joint weld quality, spotting inter-turn short circuits, ensuring voltage tap changers make secure contact at every position (and that actual vs. indicated positions match), checking for lead wire breakage, and detecting broken strands in multi-strand windings.
Designed to meet the demand for fast transformer DC resistance testing, our XX10A DC Resistance Tester integrates state-of-the-art power supply technology. It stands out with its compact size, light weight, high output current, consistent performance, strong anti-interference ability, and full protective features. Powered by a high-speed MCU, it offers seamless automation—including automatic discharge and alarm functions to prevent hazards. Boasting high accuracy and simple operation, the XX10A streamlines rapid DC resistance measurement for transformers, making it a go-to solution for power industry professionals.
