Megger Frax 150 Sweep Frequency Response Analyzer

One of the most important parts of the transmission and distribution infrastructure of today is the power transformer. Transformer failures result in unplanned maintenance and unplanned outages that cost a lot of money. It’s critical to prevent these errors and ensure that testing and diagnostics are effective and dependable.

Potential mechanical and electrical issues are identified by the Megger FRAX 150 Sweep Frequency Response Analyzer (SFRA) in ways that other techniques cannot. For over ten years, the FRA technique has been utilized by major utilities and service providers.

Megger FRAX 150 detects problems such as:

• Winding deformations and displacements
• Shorted turns and open windings
• Loosened clamping structures
• Broken clamping structures
• Core connection problems
• Partial winding collapse
• Faulty core grounds
• Core movements
