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...

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

Summary form only given, as follows.

Parameter measurements to study surge propagation in induction machines
2004 Edition, Volume 40, September 1, 2004 - 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 Characteristics of Pipe Enclosed Underground Cables
1978 Edition, Volume PAS-97, September 1, 1978 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The complex propagation constant and the impedances of a pipe-enclosed cable are studied at the high frequencies common to transmission line surges. The case of eccentric cable positions within the...

Simulation of lightning surge propagation from distribution line to consumer entrance via pole-mounted transformer
2004 Edition, Volume 19, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This article presents a comparison between simulation and laboratory-test results of lightning surge propagation from a distribution line to a consumer entrance via a pole-mounted transformer. The simulation result, obtained using a transformer model...

The effects of laminations on steep fronted surge propagation in large AC motor coils
1990 Edition, Volume 5, March 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To date, the modeling of machine windings for steep fronted surge propagation has been based on an assumption that the slot walls act as flux barriers at the frequencies of interest (1 to 10 MHz). This assumption led to the use of a...

Comparison of corona models for computing the surge propagation in multiconductor power lines
2016 Edition, June 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Different corona models are investigated with reference to the propagation along lossy overhead multiconductor transmission lines of overvoltages due to direct lightning strokes. A nonlinear dynamic capacitance is introduced to simulate the nonlinear behavior of...

Modeling of effects of laminations on steep fronted surge propagation in large AC motor coils
1989 Edition, January 1, 1989 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The modeling of machine windings for steep-fronted surge propagation has been based on an assumption that the slot walls act as flux barriers at the frequencies of interest (1 to 10 MHz). The assumption is valid for a solid slot environment,...

Experimental setup for the measurement of surge propagation in induction machines
2004 Edition, Volume 19, December 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents the experimental setup for the measurement of surges and their propagation within the turns of a coil in an induction machine. Recent advances in data capture techniques makes this work possible, which will...

A multiconductor transmission line model for surge propagation studies in large a.c. machine windings
1990 Edition, January 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

An analytical model (a frequency-dependent transients program) was developed to predict turn and interturn voltages across the line-end coil under steep-fronted surge conditions. The results of simulation for laminated and solid slot cases showed a close...
