Transformer Winding Deformation Tester (SFRA)|XHBX1501S
Introduction
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.
Key Features

Who Is It For
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.
Product Details
FAQ
1. Who is this SFRA tester designed for?
It is built for transformer manufacturers establishing pre-delivery deformation baselines, power utilities diagnosing transformers after short-circuit events, and inspection agencies performing preventive tests on 63kV-500kV units.
2. What does three-phase simultaneous measurement mean for my workflow?
It sweeps all three phases in one operation, cutting test time significantly compared with single-phase testing and providing a complete deformation picture in a single run.
3. Can it detect winding deformation without opening the transformer?
Yes. Using frequency response analysis (FRA), it detects internal winding deformation caused by short-circuit impact or transport without lifting the cover or disassembling the transformer.
4. What standard does it comply with?
Its software and hardware meet the DL/T911-2004 standard for transformer winding deformation frequency response analysis, so results are accepted by utilities and inspection agencies.
5. How wide and accurate is its frequency sweep?
It sweeps 10Hz-10MHz with 40000 points, a -120dB~+20dB amplitude range and 0.1dB accuracy, producing detailed amplitude-frequency and phase-frequency curves for reliable diagnosis.
