Megger FRAX 150 With accessories, 9 m cable set. Price on application.
Power transformers are some of the most vital components in today’s transmission and distribution infrastructure. Transformer failures cost enormous amounts of money in unexpected outages and unscheduled maintenance. It is important to avoid these failures and make testing and diagnostics reliable and efficient.
Major utilities and service companies have used the FRA method for more than a decade and the method is covered in international standards. The measurement is easy to perform and will capture a unique fingerprint of the transformer.
The Megger FRAX sweep frequency response analyser (SFRA) detects potential mechanical and electrical problems that other methods are unable to detect.
The Megger FRAX detects problems such as:
Winding deformations and displacements.
Shorted turns and open windings.
Loosened clamping structures.
Core connection problems.
Partial winding collapse.
Faulty core grounds.
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 are stored on the built-in hard drive. The data can be moved to any other computer using a USB memory stick.
The FRAX software provides numerous features for efficient data analysis. Unlimited tests can be open at the same time and the user has full control of which sweeps to compare. The response can be viewed in traditional magnitude vs. frequency and/or phase vs. frequency view.
Includes: Generator cable Measure cable, 4 x 3 m (10 ft) ground braid set, 2 x 0.3 m (1 ft) braid with clamp, 2 x C-clamp (bushing connector clamp), 2 x G-clamp (ground clamp), Field Test Box FTB101, Ground cable 5 m (15 ft), Mains cable, FRAX software for Windows, user manual and a canvas carry bag for the accessories.
