Abstract

Results of an experimental investigation of gas formation due to the decomposition of some insulating liquids under the stress of PD (partial discharges), heat, and ultrasonics are given. The investigation was performed on a special device providing full analysis of gaseous decomposition products. This device excludes losses of the gases formed, allows the possibility of liquid mixing and provides for the insulating liquid test for chromatographic analysis. It is proposed that the method of ultrasonic stress be used for primary evaluation of insulating liquids for their application in high-voltage capacitors
