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.



  • 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.


  • Transformer faults detected in their infancy, minimizing costly unplanned outages and equipment failure.
  • Transformer output optimized safely, maximizing your assets.
  • Photo Acoustic Technology – no costly consumables/calibration gases required.
  • Type of fault may be indicated from results.


  • DGA & Water – Three fault gases (Hydrogen, Acetylene and Carbon Monoxide) plus moisture.
  • Load sensor input and outputs.
  • Easy Installation – Simple, straightforward procedures.
  • Hourly Sampling – Real-time DGA results down to once per hour.
  • Perception – PC software allows downloading, trending and analysis of results.
  • 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.
