Estimation of Re-striking Transient Overvoltages in a 3-Phase 132KV Gas insulated Substation
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 4
Abstract
This paper presents the most significant results of a Very fast transient Overvoltages generated due to switching operations have been analyzed and presented. Since the contact speed of dis-connector switches is low, re-striking occurs many times before the current interruption is completed .Each re-striking generates transient overvoltage with level of magnitude. These transient have travelling wave behaviour, they travel to the external systems through enclosures, bushings, cable joints etc.. and cause damage to the outside equipment. They can lead secondary break downs in GIS and may give rise to electromagnetic interference. The Earth faults give rise to TEV which can interfere with the operation and control of secondary equipment in a 3-phase 132kv GIS. Thus it is important to develop a suitable MATLAB7.8 models for estimation of these overvoltages.
