The XHBX1501 Transformer Winding Deformation Tester employs Frequency Response Analysis (FRA)—the internationally recognized method for non-destructive detection of internal transformer winding faults. Fully compliant with DL/T911-2016, this instrument quantifies changes in winding frequency response characteristics caused by mechanical deformation, displacement, and electrical faults including inter-turn short circuits. By comparing frequency response curves across phases (horizontal analysis) and against historical baselines (vertical analysis), the XHBX1501 precisely identifies the type, location, and severity of winding anomalies in 63kV to 500kV power transformers without requiring oil drainage or core disassembly.
At its core, the XHBX1501 features a 16-bit dual-channel high-speed A/D converter driven by DDS (Direct Digital Synthesis) digital sweep technology sourced from the United States, delivering 40,000-point linear frequency sweeps from 10Hz to 10MHz with 0.1dB amplitude accuracy. A built-in expert diagnostic system automatically classifies winding condition into four consistency grades, generates complete Word-format test reports, and supports simultaneous loading of up to six historical curves for trend analysis. With USB, WiFi, and Bluetooth connectivity, the instrument pairs seamlessly with Windows laptops, Android tablets, and smartphones for maximum field flexibility.
