Toga GC 2 explained in one minute
Explained in one minute: how the TOGA GC 2 from Energy Support analyses insulating oil for all 11 dissolved gases using mercury-free vacuum degassing and gas chromatography, detecting transformer faults early – compliant with ASTM D3612 and IEC 60567.
Read the video transcript
The insulating oil of a transformer holds its entire history. Overheating and electrical discharges leave dissolved gases behind – long before a failure occurs. The Toga GC 2 makes them visible: fully automatic gas-in-oil analysis for your laboratory. Simply insert the syringe with the oil sample – no sample preparation needed. Mercury-free vacuum degassing extracts the gases from the oil and measures the total gas content at the same time. The gas chromatograph then separates all eleven gases – with a sensitivity of 0.1 ppm for hydrocarbons. The integrated expert system evaluates the result immediately – using Duval, Rogers, IEC or your own method. With the optional autosampler, you can analyze up to 32 samples in a row – compliant with ASTM and IEC. Toga GC 2. Precise oil analysis – from Energy Support.

All benefits at a glance
Fully automatic
Fully automatic process without additional sample preparation – user-friendly menu navigation via the Windows software.
Vacuum degassing
Multi-stage vacuum extraction without mercury to ASTM D3612 / IEC 60567 – with fully automatic cleaning, no carry-over.
Total gas content (TGC)
Currently the only system that measures the total gas content precisely during degassing – a clear indication of thermal, electrical or mechanical faults.
Highest sensitivity
Analysis of the 11 dissolved gases down to just 0.1 ppm for hydrocarbons – even new insulating oils can be assessed reliably.
Quick cooling
Very fast measurement sequence thanks to rapid cooling to start the next measurement – ideal for the heat-run test.
Optional autosampler
Upgradeable with an autosampler for 16 or 32 oil samples – contamination-free, reproducible series measurements.
Expert System software
The Toga GC 2 comes with the Expert System software. Apply various diagnostic methods or design your own method with individual gas concentrations as the basis for condition assessment.
Detection limits
Accuracy · ppmAll results are shown in ppm; the sensitivity for hydrocarbons is only 0.1 ppm. This makes it possible to analyse even new transformer oils and transformers after their regular maintenance.
