Three Phase Transformer Winding Deformation Tester SFRA Frequency Response Analyzer 63kV-500kV Simultaneous Measurement

The transformer winding deformation tester makes accurate diagnosis of transformer internal faults by measuring the characteristic parameters of the windings, using the frequency response analysis (FRA) method. It detects internal winding deformation caused by short-circuit current impact or during transportation without lifting the cover or disassembling the transformer. The XHBX1501S applies to internal structure fault detection of 63kV-500kV power transformers and supports three-phase simultaneous measurement, greatly reducing field testing time.

• Non-destructive testing without lifting the cover or disassembling the transformer.
• Uses the widely adopted sweep frequency response analysis (SFRA) method.
• Measures transformers rated above 6kV, covering 63kV-500kV power transformers.
• Split structure with the host and computer connected by USB or network — plug and play.
• Simple field wiring for easy operation.
• Three-phase simultaneous measurement significantly shortens test time.
• Powerful analysis software meeting the DL/T911-2004 national standard.
• Linear or logarithmic (segmented) sweep measurement.
• Multi-range response channel with automatic range adjustment during measurement.

Built for teams that must verify transformer winding integrity and diagnose deformation, the XHBX1501S serves three-phase and high-voltage testing workflows that single-phase SFRA kits cannot cover efficiently:

• Transformer manufacturers establishing pre-delivery winding deformation baselines.
• Power utilities and grid companies diagnosing transformers after short-circuit events.
• High-voltage testing and inspection agencies performing preventive deformation tests.
• Transportation and relocation teams assessing winding damage after transformer movement.
