In a GIS, Very Fast Transient Over voltages (VFTO) are generated mainly due to switching operations. The switching operation may be of a disconnect or switch or a circuit breaker or an earthling switch. These switching overvoltage levels are possible up to 3.0 p.u, depending on switching configuration .This paper deals with analysis of vftos in transformer… (More)
