Characteristic parameter analysis on the suppressing VFTO in GIS by ferrite

Proceedings of 2005 International Symposium on Electrical Insulating Materials, 2005. (ISEIM 2005)., 2005
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.

Damping of VFTO in Gas-Insulated Switchgear by a New Coating Material

IEEE Transactions on Power Delivery, 2016
Several methods of attenuation of very-fast transient overvoltages (VFTOs) in gas-insulated switchgear (GIS) are under development. An approach that is currently gaining high attention among researchers is based on the application of magnetic cores dissipating the energy associated with VFTO due to eddy current losses and magnetic hysteresis losses ...

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.
