ABSTRACT:
The quantity of SF.sub.6 gas dissolved in a halogenated dielectric coolant used in transformers can be determined by heating a sample quantity of the sample gas coolant to the point of cavitation and comparing the temperature and pressure at which cavitation first appears to a graphic representation of the relationship between concentration, pressure and temperature to obtain the gas concentration from the observed temperature point.
