The HZP-10B Transformer DC Winding Resistance Tester is designed for measuring DC resistance in transformer manufacturing, finished-product factory testing, installation, overhaul, tap changer adjustment, handover testing, and preventive testing 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, broken strands in parallel windings, and other conductor defects.
To meet the demand for rapid transformer DC resistance measurement, our company developed the HZP-10B. The instrument adopts new power supply technology, featuring a compact size, light weight, large output current, good repeatability, strong anti-interference ability, and comprehensive protection functions. The entire machine is controlled by a high-speed microcontroller with a high degree of automation, automatic discharge, and a discharge alarm function. It offers high testing precision and easy operation, enabling rapid measurement of transformer DC resistance.
