What is Frequency Response Analysis?
Frequency response analysis (commonly referred to as FRA or SFRA) is a powerful and sensitive method for testing the mechanical integrity of transformer cores, windings and press frames in power transformers.
In Which Situations Is Frequency Response Measured?
We recommend testing the frequency response, especially after the following situations:
- After the transport of transformers
- After faults occur at high currents
You can use our MTKZ-902 Frequency Response Analyzer to check if the windings are damaged and then start any other actions that may be necessary.
