The Effect of Cloud-to-Cloud Lightning on Medium Voltage Lines

Electromagnetic Fields from Cloud-to-Cloud Horizontal Lightning Channel on Perfect Conducting Soil: Induced Potentials in Flying Aircraft

“…Due to the difficulties described before with zero frequency, very few contributions tackle this problem [6]. On the other hand, the study of horizontal cloud-to-cloud lightning channels is difficult to find in the literature, perhaps because their effects at ground level are too small to represent a problem, although this may not be entirely true [7][8][9]. However, some installations, such as communication antennas or power lines, are located at a certain height above mountain peaks or elevated buildings, which shortens the distance to the horizontal channel, potentially generating significant disturbances in the installations with respect to their normal behavior.…”

Computation of Electric and Magnetic Fields Generated by Cloud-to-Cloud Lightning Channels

“…However, in the last two decades, greater attention to cloud discharges has resulted in increased interest due to their potential direct or indirect effects on aircraft and spacecraft [16,17], especially when, for weight reduction and fuel savings, the metallic structure of aeroplanes and avionic systems is replaced by carbon fibre-reinforced composites [18] which provide lower electromagnetic shielding [19,20]. Furthermore, recent studies have provided evidence for the indirect effects of cloud-to-cloud (CC) lightning on overhead medium voltage lines which causes line faults due to inadequate creepage distance of line insulators during wet conditions [21]. Moreover, it should be noted that information concerning the evolution of lightning phenomena, such as the indirect derivation of lightning physical parameters (i.e., the amplitude, shape, and speed of the propagating current or the charge deposition along the channel, etc.)…”
