Megger FRAX99 Sweep Frequency

Introduction of  Megger FRAX99

The Megger FRAX99 Sweep Frequency Response Analyzer (SFRA) is a sophisticated diagnostic tool designed to assess transformers’ and other power apparatus’s mechanical and electrical integrity. This advanced instrument uses the sweep frequency response analysis technique to detect and diagnose issues within the windings, core, and structure of transformers, which are often difficult to identify through traditional testing methods.

The measurement is compared with the reference fingerprint and gives a direct answer as to whether the mechanical parts of the transformer have not changed. The offset indicates geometric and/or electrical changes in the transformer.
