The HZP-10B Transformer DC Resistance Tester is designed for measuring DC resistance in transformer manufacturing, factory acceptance testing, installation, overhaul, tap-changer adjustment, handover testing, and preventive maintenance by power departments. It verifies the welding quality of winding joints, detects turn-to-turn short circuits, confirms the contact condition and position accuracy of voltage tap-changers, and identifies lead wire fractures or broken strands in parallel windings.
To meet the demand for rapid DC resistance measurement, our company developed the HZP-10B. The instrument adopts advanced power supply technology, offering a compact size, light weight, high output current, excellent repeatability, strong anti-interference capability, and comprehensive protection functions. The entire unit is controlled by a high-speed microcontroller, delivering a high degree of automation, automatic discharge, and discharge alarm functions. It provides high testing precision, simple operation, and enables fast measurement of transformer DC resistance.
