DANI Transformer Oil Gas Analyzer

Transformer Oil Gas Analyzer – TOGA

Transformer-oil gas analysis (TOGA) is required as a test of oil-filled electrical transformers condition. When a fault in a transformer occurs, certain gaseous products appear. The relationship between the amounts of the various compounds and the various types of fault is generally understood, so an early diagnosis by performing a routine TOGA analysis results as a prevention of future failures.


This method covers the procedure for extraction and measurement of gases dissolved in electrical insulating oil having a viscosity of 20cSt or less at 40ºC, following the ASTM D 3612-C Method. The gases to be measured include Hydrogen (H2), Oxygen (O2), Nitrogen (N2), Carbon Monoxide (CO), Carbon Dioxide (CO2), Methane (CH4), Ethane (C2H6), Ethylene (C2H4), Acetylene (C2H2), Propane (C3H8) and Propylene (C3H6).

The analytical method consists of the extraction of the dissolved gases by mean of the Headspace sampling technique. A portion of the headspace phase in equilibrium with the oil is sampled and automatically introduced into a gas chromatographic system.
