Overview

Megger's The FRAX series of sweep frequency response analyzers (SFRA) de-tects mechanical and electrical changes of the core and winding as-sembly of power transformers. Major utilities and service companies have used the FRA method for more than a decade and the method is covered in international standards.

Features
- Highest dynamic range and accuracy in the industry
- Fulfills international standards for SFRA measurements?
- Advanced analysis and decision support built into the software
- FRAX 150 with built in PC and touchscreen?
- Imports data from other FRA test sets?
- Battery operated (optional FRAX 99 and FRAX 101)?

Major Applications
- Smallest and most rugged FRA instrument in the industry??
- Guaranteed repeatability by using superior cabling technology and standardized signal cable grounding technique (IEC 60076-18, Method 1)??
- Fulfills international standards for Sweep Frequency Response Analysis (SFRA) measurements (IEC 60076-18, IEEE C57.149 etc).?
- Highest dynamic range and accuracy in the industry allowing even the most subtle electro-mechanical changes within the transformer to be detected.?
- Advanced analysis and support software tools allows for sound decision making with regard to further diagnostics analysis and/or transformer disposition
- Built-in PC with touchscreen
