The HZ-10K Transformer DC Resistance Tester is an essential instrument for transformer testing across the full product lifecycle — from semi-finished and finished product manufacturing, factory testing, and installation to overhauls, tap changer adjustments, acceptance testing, and preventive maintenance by power departments.
It verifies the welding quality of winding joints, detects inter-turn short circuits in windings, confirms the contact quality of tap changer positions, and ensures the actual tap changer position matches the indicated position. It also identifies broken leads, broken strands in multi-strand wires, and other faults.
Built on advanced power technology, this instrument offers a compact and lightweight design, 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 with automatic discharge and discharge alarm functions. It provides high measurement accuracy, simple operation, and rapid measurement of transformer DC resistance.
