XHZ1010SC

The XHZ1010SC DC Resistance Tester is an indispensable instrument for a wide range of transformer-related testing scenarios, such as factory tests for semi-finished and finished products, on-site installation, overhaul maintenance, tap changer adjustments, handover tests, and preventive inspections carried out by power departments. Its key capabilities include examining the welding quality of winding joints, detecting inter-turn short circuits in windings, confirming the good contact of voltage tap changers at all positions, verifying the consistency between the actual and indicated positions of tap changers, checking for broken lead wires, and identifying strand breaks in multi-strand parallel windings.

To address the industry demand for efficient and rapid DC resistance measurement of transformers, our company has developed this handheld XHZ1010SC DC Resistance Tester. Equipped with advanced power supply technology, the instrument offers remarkable advantages: compact size, light weight, large output current, excellent measurement repeatability, strong anti-interference performance, and comprehensive safety protection functions.

Controlled by a high-speed single-chip microcomputer, the tester features a high level of automation, including automatic discharge and discharge alarm functions to ensure operational safety. With its high testing accuracy and simple, intuitive operation, the XHZ1010SC effectively realizes fast and reliable DC resistance measurement for transformers, making it a practical and efficient testing solution for professionals in the power industry.
