Sweep Frequency Response Analyzers

Sweep frequency response analyzers (SFRAs) evaluate mechanical and electrical integrity of power transformers and aid in the detection of potential issues within the transformer, such as winding deformation and broken clamping structures. They work by injecting a signal across a given frequency range and measuring each transformer's response, and can be used either for routine maintenance or post-fault analysis.

ATEC offers sweep frequency response analyzer rentals from leading manufacturers such as Doble, Megger, and OMICRON.
