The Megger FRAX Series—FRAX99, FRAX101, and FRAX150—captures a transformer’s unique ‘fingerprint’ through straightforward SFRA measurements. Results are compared to baselines for quick detection of issues like winding deformations or core faults. Utilities have trusted this method for over a decade to spot problems early and avoid costly outages. Each model offers top-tier accuracy and dynamic range. Software simplifies analysis and supports data from other units. Options like battery power, wireless connectivity, or built-in PC add flexibility for lab or field work without complexity.
