Modeling Airfield Ground Lighting Systems for Narrowband Power-Line Communications
(IEEE-Institute of Electrical and Electronics Engineers, 2010)
Airfield ground lighting (AGL) systems are responsible for providing visual reference to aircrafts in the airport neighborhood. In an AGL system, a large number of lamps are organized in serial circuits and connected to ...

Modeling dispersion of partial discharges due to propagation velocity variation in power cables
(Elsevier, 2016)
Existing models for partial discharge (PD) propagation based on a single attenuation constant are unable to explain how each frequency component travels with a different propagation velocity. This paper proposes a new model ...

Effects of Dispersion and Multi-Path Propagation in Partial Discharges Location
(Institute of Electrical and Electronics Engineers Inc., 2020-11)
Dispersion and multi-path propagation distort partial discharge (PD) pulses that travel along power cables. This article proposes a theoretical framework that models the PD source location error owing to these effects. ...

Partial discharge detection using PLC receivers in MV cables: A theoretical framework
(Elsevier, 2018-11)
Partial discharge (PD) activity is a key indicator of the cable insulation health in medium-voltage networks. Many of these cables are used as transmission media, because power line communication (PLC) modems are installed ...

Time domain analysis of partial discharges envelope in medium voltage XLPE cables
(Elsevier, 2015)
Partial discharge (PD) analysis has been widely used to detect premature degradation of power cables. Although there are recognized techniques for PD analysis, there is still lack of knowledge about measuring and modeling ...

Improving partial discharges location under dispersion and multi-path propagation
(Elsevier, 2021-05)
Dispersion and multi-path propagation distort partial discharge (PD) pulses that travel along power cables. Two new techniques to improve the location accuracy using double-ended methods are proposed: the inclusion of a ...
