Transformer DC Resistance Tester 24V Temperature Conversion 7-Inch Touchscreen| XHZ1010

The XHZ1010 DC Resistance Tester is essential for all critical stages of the transformer lifecycle, from factory checks of semi-finished and 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, checking for lead wire breakage, and detecting broken strands in multi-strand windings. Integrating 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, making it a go-to solution for power industry professionals.
