TRAX Multifunction transformer and substation test system

TRAX is not just a multifunctional test instrument, but many intelligent instruments in one. The software includes several apps, making it fast and easy to perform a large range of different tests. The hardware, range of cables and accessories offers unmatched flexibility, making the TRAX an efficient and time-saving system.

TRAX is packed with functionalities to make the test engineer’s task easier and quicker. For example, the 100 A true DC test current with a 50 V compliance voltage for winding resistance measurements or the 250 V AC voltage for turns ratio measurements. Also, the adaptive technique for the fastest and most efficient demagnetisation of a transformer core and the patented technique for acquiring authentic, dynamic resistance measurements on on-load tap changers to determine the real magnitude of transition resistances and transition times. TRAX also features 12 kV power factor/tan delta testing, patented temperature correction, voltage dependence detection, and narrowband dielectric frequency response (NB DFR) testing, making it a robust transformer test system.

TRAX includes Megger’s market leading circuit breaker testing technology and is the only multifunctional test set on the market that offers the following tests:

• Timing test (O, C, OC, CO and OCO)
• Coil supply voltage (Station voltage)
• Pre-insertion resistance (PIR)
• Open coil current
• Breaker analysis graphs (timing, voltage, current)

TRAX offers full manual control of inputs and outputs – a unique tool for immediate troubleshooting. Routine procedures can be reproduced or modified using the manual control features to vary voltage, current, and/or frequency. TRAX is a portable metrology laboratory ideal for advanced users, research institutions, and root cause analysis specialists.

Manual control gives you access to control and operate:

• 10 generators (AC and DC; voltage and current)
• 6 measurement channels (AC and DC; voltage and current)
• Electrical formulae calculator
• Real-time oscilloscope
