Summary
This paper presents a new approach to determine solubility of characteristic gases considered for DGA (dissolved gas analysis) technique in insulating liquids. For this purpose, a test set-up was designed and manufactured, which rules out the problems of the so called glass syringe method. First, the solubility of several key gases are determined at 25 °C and at the pressure of 1020 mbar for a conventional mineral oil and reported as Ostwald coefficients. The measured values are consistent with those corresponding values provided by IEEE C57.104. Besides, it has been shown that the standard deviation of the measured values is in an acceptable margin, which guarantees applicability of this method to determine the gas solubility in the insulating fluids.
