Abstract

This paper describes the transient characteristics of air-gapped CTs in EHV transmission systems. An air-gapped CT is modelled using EMTP. Air-gapped CTs with the gap of 0, 0.5, 1.0 [mm] are analysed and compared with and without consideration of auto-reclosure. From the results. even small gap improves the transient characteristics after auto-reclosure.
