Multifunction transformer and substation test system

▪ Replaces need for multiple test sets
▪ Saves time by eliminating need for multiple instruments learning
▪ User-friendly interface reduces training and testing time
▪ Portable and compact system components for easy shipping
▪ State of the art measurement methods for advanced diagnostic testing

TRAX application areas can be greatly expanded by the use of auxiliary instruments:

▪ TDX120 – Accessory for tan delta /power factor up to 12 KV
▪ TCX200 – High current accessory for primary injection testing up to 2000 A
▪ TSX303 – Automated 3-phase switchbox for faster testing of power transformers
▪ TSX300 – Manual switchbox for easier connection during power transformer testing
▪ Line impedance kit – Kit for testing line impedance with TRAX

TRAX is not just another multi-functional test instrument, but rather many intelligent instruments built into one box. 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 for any user in the world.

TRAX is a multi-functional solution for transformer testing. It also adds several common substation testing functionalities, and ultimately replaces numerous individual testing devices. Compared to conventional single-functionality instruments, TRAX saves time and is more cost effective.

TRAX applications range from power transformers, where it offers several unique and outstanding features, to instrument transformers, circuit breakers, and many other substation components.
