Fault analysis of GIS Cable Terminal Kit in Railway Power System

초록

We have investigated the incident taking placed in the railway subsection substation which brought sudden blackout and stopped several running trains and gave some economical loss to operators. It was resulted from the explosion of oil-filled cable terminal kit for GIS suppling power to train power line. This paper have shown the results of electrical and chemical analyses for what caused that explosion. It has been resulted of the complexity of partial discharge and heated semiconductor flown by currents which was coming from the defects made by some variable reasons.
