Megger TRAX Transformer / Substation Test System

Megger TRAX Transformer and Substation Test System has been designed to maintain substations and measure the vital signs of current and voltage transformers, plus offers data handling and reporting.  TRAX applications range from power transformers, where it offers several unique and outstanding features, to instrument transformers, circuit breakers and many other substation components.

Power transformers are among the most expensive parts of the electrical network. Testing a power transformer is important in order to correctly assess the condition of the unit and to detect incipient faults at an early stage. The objective is to ensure safe operation and minimise the risk of outages. With a careful asset management program, it will be possible to extend the life of the power transformer while maintaining reliability.


Megger TRAX - All In One Box!

TRAX is not just another multi-functional test instrument, but rather many intelligent instruments built into one box. It also adds several common substation testing functionalities, and ultimately replaces numerous individual testing devices. The software includes a number of apps, making it fast and easy to perform a large range of different tests. The hardware offers unmatched flexibility and the range of cables and accessories adds even more flexibility, making the TRAX an efficient and time saving system.
