Development of Full Frequency Bandwidth Measurement of VFTO in UHV GIS

IEEE Transactions on Power Delivery, 2013
In order to study the characteristics of very fast transient overvoltage (VFTO) in ultra-high voltage (UHV) gas-insulated switchgear (GIS), the authors have developed a full frequency bandwidth measurement system based on a porthole-type capacitive voltage divider.

Estimating the Size of Ferrite for Suppressing VFTO in GIS

2006 IEEE 8th International Conference on Properties and applications of Dielectric Materials, 2006
The insulation of apparatus in the power system is often broken by the very fast transient over voltage (VFTO), which cause from the operation of disconnector in gas insulate substation (GIS). In this paper, a new idea for the Suppressing VFTO by ferrite is put forward, and the characteristic of ferrite is analyzed.
