UHV-100A Transformer DC Winding Resistance Tester -Catalog

Product catalog summary

Product Introduction
The UHV-100A Transformer DC Winding Resistance Tester is essential for various transformer tests, including factory, installation, overhaul, and preventive tests. It checks the welding quality of winding joints, detects inter-turn short circuits, verifies tap changer positions, and identifies broken strands in wires. The tester is designed for rapid measurement with features like small volume, light weight, large output current, and strong anti-interference capabilities. It is controlled by a high-speed microcomputer, offering high automation, accuracy, and simple operation.
