The Transformer DC Winding Resistance Tester is designed for inspection, installation, debugging, and preventive testing of semi-finished and finished products in transformer manufacturing. This instrument effectively detects hidden hazards and operational defects including material selection issues, welding problems, loose connections, short circuits, and fractures in transformer coils.

Developed to meet the demands for rapid transformer DC resistance measurement, the CT series DC resistance tester features microcontroller control with automated self-inspection, data processing, display, storage, and printing capabilities. Combined with precise electronic measurement technology, this instrument offers high accuracy, wide measurement range, and user-friendly operation for efficient measurement of transformer sensitivity, voltage, and resistance.
