 MGR-FRAX150 Sweep Frequency Response Analyzer


o Smallest and most rugged FRA instrument in the industry
o Highest possible repeatability by using reliable cable practice and
high-performance instrumentation
o Fulfills all international standards for SFRA measurements
o Highest dynamic range and accuracy in the industry
o Built-in PC with powerful backlit screen for use in direct sunlight
o Advanced analysis and decision support built into the software
o Imports data from other FRA test sets

The FRAX 150 Sweep Frequency Response Analyzer (SFRA) detects potential mechanical and electrical
problems that other methods are unable to detect. Major utilities and service companies have used
the FRA method for more than a decade. The measurement is easy to perform and will capture a
unique "fingerprint" of the transformer. The measurement is compared to a reference
"fingerprint" and gives a direct answer if the mechanical parts of the transformer are
unchanged or not. Deviations indicate geometrical and/or electrical changes within the
transformer.

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

FRAX 150 has a built-in PC with a high contrast, powerful backlit screen
suitable for work in direct sunlight. The cursor is controlled via the
built-in joystick or using an external USB mouse and the built-in keyboard
makes data entry easy.
All data is stored on the built-in hard drive. The data can be moved to any
other computer using a USB memory stick.
