FRAnalyzer
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.
