ABSTRACT
This paper describes the VFTO are usually Transient vervoltages in a gas insulated substation. A few Gas Insulated Substation (GIS) units have been in operation and large number of units are under various stages of installation. These problems include, generation of the overvoltage during Dis-connector operations, line to enclosure faults. The fast transient overvoltages obtained are due to switching operations and with fixed arc resistance and variable arc resistance for different lengths of GIS. The Transients are calculated along with load and it was observed that the transients obtained in 5mts length GIS will affect the system more than that obtained in 10mts length GIS and control of secondary equipment in a Single-phase 220kv GIS. The variable arc resistance is calculated by Toepler’s formulae. The equivalent circuits are developed for the components of GIS and voltages are calculated by using the Matlab 7.8 software.
