Omicron FR Analyzer (FRA)


FR Analyzer

The FRAnalyzer (Frequency Response Analyzer) was developed for winding diagnostics on power transformers. It performs a frequency response test to ensure that windings are not damaged following transportation of transformers or occurrence of high currents. The FRAnalyzer uses the SFRA principle (Sweep Frequency Response Analysis). It detects winding defects and faults in the magnetic core - thereby helping to improve transformer reliability, reduce maintenance costs and prevent costly failures.

Key Features

  • Reproducible results thanks to innovative connection technology
  • Extremely small and compact device (<1.8 kg)
  • Wide dynamic measuring range (>120 dB)
  • Fast measurement times (around 30 seconds per measurement)
  • Experienced Omicron experts help with the interpretation of measurement results

The FR Analyzer is used for transformer testing, following:

  • a short circuit
  • transport
  • occurrence of highly transient fault currents
  • a significant change in the monitored values (e.g. combustible gases) or a safety shutdown
  • Coupling of power lines into signal cables

The following tests can also be performed:

  • Routine transformer condition measurement
  • Verification of unusual events determined during conventional testing
