FRAnalyzer
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.
The OMICRON FRAnalyzer detects mechanical and electrical changes of the core and winding assembly of power transformers. By finding winding or core defects after faults, mechanical shocks (e.g. earthquakes) or transportation, it offers a valuable opportunity to improve the reliability of transformers, to reduce maintenance costs and, most of all, to avoid expensive unexpected outages.
Detects the following
- winding deformation – axial & radial, like hoop buckling, tilting, spiraling
- 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
- problematic internal connections
