Surge propagation in three-phase pipe-type cables▀×Part II: Duplication of field tests including the effects of neutral wires and pipe saturation
1977 Edition, Volume 96, May 1, 1977 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Field tests of surge propagation in 69-kV pipe-type cables are successfully duplicated using an analytical model. The solution techniques are general and can be applied for any waveshape or travel time. Included in...

Lightning Surge Propagation on a Grounded Vertical Conductor
2018 Edition, Volume 60, February 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter addresses lightning surge propagation on a vertical conductor connected to the earth via a ground electrode. As the vertical conductor does not support the TEM mode of wave propagation, surge propagation is characterized...

Lightning Surge Propagation on a Single Conductor in Free Space
2017 Edition, Volume 59, February 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper introduces an analysis of lightning surge propagation on a conductor without any returning current path. The conductor can be either a free-space or grounded conductor as long as the reflected surge from the ground has not arrived. Unlike...

Surge propagation characteristics on nonuniform lines
2008 Edition, September 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper describes lightning surge propagation characteristics on a nonuniform line are dependent on location. The propagation characteristics of the nonuniform line are different from those of the uniform one due to multiple reflections on...

Measurement of surge propagation in induction machines
2003 Edition, Volume 2, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Winding failures in induction machines have been a major concern in the past several years, and more so recently with the addition of variable speed drives (VSDs). Both the introduction of the vacuum breaker, and the use...

Surge Propagation in Gas Insulated Substation
1981 Edition, Volume PAS-100, June 1, 1981 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Surge propagation performance in a 550 kV gas insulated substation is studied experimentally and by computer simulation using the Electro-Magnetic Transients Program. Extra capacitance added to the system by the components of GIS such as...

Surge propagation and characteristics in building wiring systems
2014 Edition, October 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents an experimental study of propagation characteristics of lightning surges in building wiring systems. Typical power cables or cable installations used for power distribution in buildings are selected for measurement. The influence...

Surge Propagation Characteristics on Submarine Repeatered Line
1978 Edition, Volume 26, October 1, 1978 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Lightning and cable fault induces surge current on a coaxial cable repeatered line. The surge current front becomes more and more steep when passing through the repeaters. Larger surge current penetrates the amplifier in the...

Modelling of corona dynamics for surge propagation studies
1994 Edition, Volume 9, July 1, 1994 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A computer simulation of the dynamics of corona on transmission lines has been established, and implemented into a previously developed corona model, thus making possible its accurate application to fast transient conditions. The model is based on a macroscopic...

Improved modelling of corona for surge propagation studies
1995 Edition, January 1, 1995 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A previously developed physical corona model is improved by introducing the streamer extinction field as a simulation parameter. In the model used to reproduce experimental charge-voltage curves, for different surge polarity, conductor radius and weather...
