GIS Disposal for extra high Voltages

The study of very fast transient over voltages (VFTO) for ...This ratio decreases when we go for extra high voltages. Therefore the insulation for extra high voltages should be carefully designed to avoid the dielectric failures. Very fast transient over voltages (VFTO) which are caused by the switching operations are the important factors to be considered in the design of GIS.
