OMICRON FRAnalyzer Frequency Response Analyser

Click2Contact

The OMICRON FRAnalyzer is a transformer tester that uses Sweep Frequency Response Analysis (SFRA) to detect mechanical and electrical changes in the core and winding assembly of power transformers. It is available to rent from TechRentals.

By identifying a power transformer’s unique frequency response, SFRA can be used to diagnose issues without the need for expensive demounting of a transformer’s active part. The integrity of the transformer can also be verified after a fault, mechanical shock or transportation. Regular, ongoing analysis can improve reliability and prevent a costly outage.

The product has a frequency range of 10 Hz to 20 MHz (selectable) with dimensions 26 x 5 x 26.5 cm (W x H x D), as well as fully customisable sweep settings.

The device’s fault detection applications include: winding deformation — axial and radial, such as hoop buckling, tilting and spiralling; displacements between high- and low-voltage windings; partial winding collapse; shorted or open turns; faulty grounding of core or screens; core movement; broken clamping structures; and problematic internal connections.

The package comes with a laptop preloaded with FRAnalyzer software.
