Routine for Simulating Transmission Lines with Symmetrical and Asymmetrical Configurations Using a Real and Constant Modal Transformation Matrix
(Ieee, 2018-01-01)
Modal analysis is widely used in over-voltage and over-current studies of power systems. Modal transformation decouples a transmission line into its modes. Time-domain transmission line models usually require a real and ...

Pair approximation for a model of vertical and horizontal transmission of parasites.
(Águas de Lindóia, 2014-01-29)
We apply Stochastic Dynamics method for a differential equations model, proposed by Marc Lipsitch and collaborators (Proc. R. Soc. Lond. B 260, 321, 1995), for which the transmission dynamics of parasites occurs from a ...
Some considerations about a new procedure to derive transmission line parameters concerning three-phase lines
(2006-12-01)
The paper shows an alternative methodology to calculate transmission line parameters per unit length and to apply it in a three-phase line with a vertical symmetry plane. This procedure is derived from a general procedure ...
Overvoltage Analysis of Transmission Towers Considering the Influence of Tower-Footing Impedance
(Ieee, 2017-01-01)
Lightning is one of the main causes of outages due to backflashover mechanism in power systems. In this context, the tower-footing impedance presents a key role in the overvoltages caused by this phenomenon. Tower-footing ...

An alternative procedure to decrease the dimension of the frequency dependent modal transformation matrices: Application in three-phase transmission lines with a vertical symmetry plane
(2006-12-01)
The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is ...
Analysis of the influence of baffles and shields on the cooling of a digital transmission equipment
(Institute of Electrical and Electronics Engineers (IEEE), 1996-01-01)
In this work design criteria for cooling of electronic systems used in a digital transmission equipment are considered. An experimental study using a simulated electronic equipment in which vertically oriented circuit ...
