In new substation construction or renovation projects, design selection personnel need to confirm whether a winding deformation tester can cover the testing requirements of transformers at different voltage levels. The WFX-8100 Transformer Winding Deformation Tester adopts the frequency response analysis method, with a sweep frequency range covering 500Hz to 2000kHz, and can perform winding deformation testing on power transformers at voltage levels from 35kV to 500kV. Before testing, all external connection lines of the transformer must be removed to avoid the influence of lead distribution parameters on test results.
On-site testing often faces power frequency supply fluctuations and electromagnetic interference. The WFX-8100 uses a single-phase power input and internally generates a stable test signal, so test results are not affected by fluctuations in power frequency supply frequency and amplitude. The instrument features good shielding and grounding design, making it suitable for substation on-site working environments and providing a reliable testing method for design selection.
Winding deformation testing is mainly used to evaluate winding condition after a transformer has suffered a short-circuit impact, transportation vibration, or major overhaul. The WFX-8100 provides amplitude-frequency response and phase-frequency response curve comparison functions, enabling longitudinal comparison with historical data of transformers of the same model or lateral comparison of three-phase winding consistency. Test data can be stored and exported, making it convenient for selection personnel to evaluate the long-term health status of equipment.
The WFX-8100 has a sweep frequency range of 500Hz to 2000kHz, frequency accuracy better than 0.01%, and a measurement dynamic range greater than 80dB. The power supply is AC 220V±10%, 50Hz, and the overall power consumption is less than 100W. The working environment temperature is -10℃ to 50℃, and relative humidity is not greater than 85%. The instrument weighs about 8kg, making it easy to carry on site.
