The MULTITRANS is an 9-gas on-line transformer DGA monitoring unit designed to monitor a bank of three single-phase transformers in close proximity. Based on the same core technology as the highly successful TRANSFIX the MULTITRANS measures all significant fault gases (in ppm) as outlined by international standards as well as moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect and diagnose a complete range of transformer faults.




  • Transformer faults detected in their infancy, minimizing costly unplanned outages and equipment failure.

  • Single unit used to monitor a bank of 3x single phase transformers.

  • Photo Acoustic Technology – no costly consumables/calibration gases required.

  • Remote assessment of fault type and severity.

  • Complete monitoring and diagnostics of transformers from results.

  • Designed for field use – global installation by almost all major utilities.



  • DGA & Water – Nine gases (hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide, carbon dioxide, nitrogen and oxygen) plus moisture.

  • Inputs/Outputs for additional sensors including load and oil temperature.

  • Hourly Sampling – Real-time DGA results down to once per hour.

  • Communication Options – Extensive local and remote communications options.

  • Alarm Settings – Sophisticated programmable alarm system.

  • Acceleration of sampling rate – automatic increase in sampling rates if gas concentrations exceed caution or alarm settings.

  • Minimal Maintenance – Reduces expense and inconvenience for user.

  • Easy Installation – Simple, straightforward procedures.



  • Monitoring a bank of three single-phase transformers in close proximity

  • Medium/High/Critical risk and/or consequence of failure.

  • Generation, Transmission and industrial transformers.

  • Complete transformer monitoring and diagnostics.
