从China供应商批发进口5a Transformer Dc Winding Resistance Tester — FOB条款

The 5A Transformer DC Winding Resistance Tester is a microcomputer-controlled instrument designed for measuring the DC resistance of transformer windings, a critical test for detecting faults such as broken strands, poor welding, or short circuits between layers and turns. The device employs four-end measurement to eliminate errors caused by line resistance and uses current-source line-based compensation technology for stable, high-precision results. Its interface features a backlit Chinese LCD screen for clear operation prompts, and it includes overvoltage protection to withstand electrical surges. Optional panel printers allow immediate documentation of test results.

Built for field and lab use, the tester is compact and lightweight, making it easy to transport between test sites. It supports analysis of all transformer types, including power transformers and distribution units, and is compliant with standard power industry testing protocols for DC resistance measurement. The instrument’s design prioritises efficiency, reducing operator workload by automating prompts and procedures. Typical industry applications include routine maintenance, pre-test inspections, and fault diagnostics in electrical grids.

Primary buyers are power utilities, transformer manufacturers, and electrical testing labs requiring reliable, repeatable resistance measurements. The tester is supplied from Wuhan, with technical support available for integration into existing test workflows. Buyers should confirm compatibility with their transformer models and voltage classes, as well as the availability of regional calibration services. Lead times and packaging details are provided upon request.
