Measurement of frequency response analysis (FRA).

Frequency response analysis (FRA or SFRA) is a sensitive method for testing the mechanical integrity of cores, windings in transformers. Every transformer has a unique frequency response, its so-called 'fingerprint'. Mains faults or vibrations can cause changes in this frequency response. measurements should be carried out at various stages and provide indications of any mechanical or electrical changes. It is advisable to test the frequency response particularly after: transport or after high-current faults You can use our test solution to check whether the windings have been damaged and then initiate any further action required.
