The MINITRANS is a low-cost on-line discrete multi-gas DGA transformer monitoring unit.

Based on the same core technology as the highly successful TRANSFIX, the MINITRANS is a lower cost alternative, monitoring three key gases: Hydrogen, Acetylene and Carbon Monoxide (in ppm) plus moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect a wide range of developing faults including arcing.




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

  • Type of fault may be indicated from results.

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


  • DGA & Humidity – Three fault gases (Hydrogen, Acetylene and Carbon Monoxide) plus moisture.

  • Easy Installation – Simple, straightforward procedures.

  • 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.


  • Medium and large sized transformers.

  • Low/medium risk and/or consequence of failure.

  • Distribution, Transmission and industrial transformers.

  • Discrete level of gases for entry level diagnostics.
