Doble M5400 Sweep Frequency Response Analyzer

For Sale Doble M5400 Sweep Frequency Response Analyzer. This unit is in excellent condition, has been fully tested and is guaranteed functional.

The Doble M5400 is a field-ready Sweep Frequency Response Analyzer (SFRA) used to assess the mechanical integrity of transformer cores and windings. It works by injecting signals over a broad frequency range to detect deformations, movements, or faults, providing a “fingerprint” for comparing transformer condition over time.

Key Features and Capabilities

• • Diagnostic Power : Identifies winding deformation, displacement, buckling, and faulty core grounds.
  • Measurement Range : Operates across a wide frequency spectrum with a dynamic range of 80 dB and ±1 dB accuracy.
  • Data Analysis : Uses Doble SFRA Software to analyze results, compare to baseline data, and detect changes.
  • Field-Ready : Rugged design suitable for site testing after transportation or system faults.

Applications

• • Commissioning : Taking baseline measurements for new transformers.
  • Routine Maintenance : Monitoring long-term transformer health.
  • Post-Event Inspection : Assessing damage after short-circuit faults, earthquakes, or transport.

Kit Components

• • Doble M5400 test set.
  • SFRA software.
  • 60 ft (18 m) SFRA test leads.
