Abstract
A 275/22 kV capacitive coupled substation (CCS) that is based on the principles of a capacitive voltage transformer (CVT) was built in the Kwa-Zulu Natal province of South Africa to supply a pumping load of 1.5 MW. During commissioning of the CCS, it was found that interaction between an induction motor and the CCS resulted in a severe voltage instability or sub-synchronous resonance (SSR). The results of various field tests done to quantify and analyse this SSR are described in this paper
