The Electric Power Engineering Handbook, Third Edition updates coverage of recent
developments and rapid technological growth in crucial aspects of power systems, including …

Switching operations in gas-insulated switchgear (GIS) substations generate transient
electromagnetic fields in the GIS pipes. These fields leak out discontinuities of the GIS and …

In IEC 60071-1 and 62271-102, there is neither standard voltage shape nor standard peak
value for very fast transient overvoltages (VFTO). Previous work by other researchers had …

This paper investigates the effect of mode transition from low-frequency transverse
electromagnetic (earth-return wave) to high-frequency Sommerfeld-Goubau (surface wave) …

This paper performs thorough investigations of very fast transients (VFTs) in a 500 kV gas-
insulated substation (GIS) by adopting complete earth-return impedance and admittance …

The transient fields generated during switching operations in gas-insulated substations
(GIS) can have rise times in the order of a few nanoseconds. Transient fields, which are …

In this paper, first transient waves in the gas-insulated substation (GIS) are analyzed and
methods for suppression of very fast transients (VFTs) in GISs are introduced. For …

Very fast transient overvoltages (VFTOs) and the associated very fast transient currents
(VFTCs) generated during switching operations in a gas-insulated substation (GIS) radiate …

This paper is focused on the oscillating frequencies of very-fast transients (VFTs) generated
by disconnector and circuit breaker operations in gas-insulated substations (GISs) related to …

There are typically large circulating current losses when such a current is produced in a gas-
insulated switchgear (GIS). An excessive circulating current also causes a heating …
