What is Dissolved Gas Analysis?
A quantitative analysis of all dissolved gases in the
transformer oil. The analysis is done after the extraction of
the gases and a gas chromatography thereafter.
The aim of the analysis is an early determination of aging
and functional problems of the transformer.

The Use of Atmospheric Gases
N2 and O2 are indispensable for the evaluation of the transfomer condition
N2: Referenzvalue for the gas saturation.
O2: Very important indicator for the ageing process

The Use of Secondary Gases (Propan and Propen)
The ‘Memory‘ of Thermic Faults
Due to the slow solubility of C3H6 and C3H8 both gases serve as a memory of Thermic faults.
