The Megger TRAX 280 Transformer & Substation Test System is a multifunctional instrument designed for primary injection testing of protective relay equipment, as well as other applications that require high variable currents, such as testing the turns ratio of current transformers. To this end, it delivers a high current output of up to 800A.

Convenience, ease-of-use, and performance are at the forefront of the Megger TRAX 280 Transformer & Substation Test System’s design. It includes an array of measurement capabilities and functions intended to improve the ease and efficiency of testing as well as reduce the number of instruments required to carry out inspections without compromising on reliability and accuracy. Therefore, the Megger TRAX 280 Transformer & Substation Test System offers:

  • State-of-the-art winding resistance and tap-changer testing
  • 100A DC test current for winding resistance measurements
  • 250V AC voltage for turns ratio measurements
  • 100A/ 50V compliance
  • Adaptive demagnetisation: enables fast and efficient demagnetisation of the transformer core
  • Patented technique for dynamic measurements on load tap-changers
  • Tap-changer control
  • DC resistance measurements with dual-ground capability
  • High-voltage ratio measurement (250V and 2200V output)
  • Patented individual temperature correction (ITC)
  • Patented automatic voltage dependence detection (VDD)
  • CT and VT testing
  • 3-phase circuit-breaker analyser (main and resistor contacts)
  • Manual phase-angle meter
  • Manual ground/ earth impedance testing
  • Contact resistance
  • Line impedance/ K-factor
  • 4-channel power multimeter
  • Oscilloscope

In addition to the above, the Megger TRAX 280 Transformer & Substation Test System supports OPTIONS for switchbox 3-phase/ 6-winding measurements and 12kV tan delta (power factor) and capacitance testing. Moreover, when used with Megger’s TCX 200 High-Current Box, the Megger TRAX 280 Transformer & Substation Test System can deliver a current output of 2000A.

The Megger TRAX 280 Transformer & Substation Test System is a comprehensive, convenient, and simple-to-use multifunctional substation test system.
