HV‑HIPOT TFR‑800 SFRA Transformer Winding Deformation Tester

Recently, HV‑HIPOT launched the new‑generation TFR‑800 Transformer Winding Deformation Tester, a professional SFRA (Sweep Frequency Response Analysis) test instrument for power transformer winding mechanical condition diagnosis.

Transformer windings may suffer displacement, bulging and distortion caused by short‑circuit impulse, transportation vibration and long‑time operation aging. Adopting frequency‑response analysis principle, TFR‑800 completes non‑destructive inspection without transformer tank lifting or disassembly. By collecting amplitude‑frequency characteristic curves and comparing with reference fingerprint data, engineers can judge winding deformation status quickly on‑site武汉国电西....

Fully compliant with IEC 60076‑18, IEEE C57.149 and DL/T 911‑2016, this tester is widely applied for power plants, substations, transformer manufacturers and third‑party testing laboratories global‑wide.

Core advantages of TFR‑800

Wide frequency sweep range, support linear & segmented sweep modes for routine test and subtle defect detection

High test repeatability, stable anti‑interference performance for complicated field substation environment

Built‑in industrial touch screen, no external laptop required; real‑time curve display, data storage, comparison analysis & automatic report generation

Portable rugged hard case design, convenient for field mobile testing

Now TFR‑800 has been delivered to multiple overseas power project sites. Customers use this SFRA device for pre‑commissioning acceptance test, periodic preventive maintenance and post‑fault assessment of 6kV‑500kV power transformers.
