This programme is concerned with issues arising from an increasingly large high voltage cable population. This includes cable ratings, mitigation of oil contamination and the identification of fault gasses.
The final project addresses the determination of solubility (Ostwald) coefficients of diagnostic gases in linear alkyl benzene (LAB) fluid used in high voltage cables. The coefficients are required to perform dissolved gas analysis (DGA) accurately when using a headspace sampling technique
