New Testing Service

We added a new testing service to our menu:

“Doble Sweep Frequency Response Analysis for Power Transformers”

This new testing service and analysis is a powerful and sensitive method to evaluate the mechanical integrity of the core, windings and structures within power transformers by measuring their electrical response over a wide frequency range.  SFRA is a proven method for evaluating transformers.  Change could be due to lightning or overvoltage transients, short circuits or changes to transformer geometry (i.e. shipping).

This service can be provided along side of other valuable transformer testing:

  • Oil Quality/Dissolved Gas Analysis
  • Transformer Turns Ratio
  • Insulation Resistance
  • Doble Power Factor
  • Electrical Load Measurement
  • Harmonic Analysis
  • Transformer Failure Forensics
  • Oil Degasification
  • Overload evaluation
  • Leaking bushings
  • Retro fill with FR3 Fluid or Transformer Oil
