Product description

Built-in computer
The instrument is completely self-contained, with an integral PC that has a high-resolution colour screen featuring a powerful backlight that makes it easy to read even in direct sunlight. It also has an internal rechargeable battery, allowing it to be used in locations where no mains supply is available.
Reveals wide range of transformer faults
Meeting all international standards for SFRA measurements, this innovative instrument offers a larger dynamic range and better accuracy than any other comparable test set currently available. In addition, for the test connections to the transformer, it makes use of special cabling technology that ensures repeatability of results.

The FRAX 150 operates by applying a sweep frequency test signal to the transformer and monitoring its response. The result is a unique fingerprint which, when compared with a reference fingerprint for the same transformer, reveals a wide range of faults. These include winding deformations and displacements, shorted and open windings, loose and broken clamping structures, core connection problems, core movement and hoop buckling.

Highest dynamic range and accuracy
Megger's FRAX 150 incorporates powerful analysis and decision support software. In addition to offering the traditional magnitude versus frequency/phase display, this software also allows users to present data in an impedance or admittance versus frequency view, which is a powerful analytical tool for many types of transformer.
