Over the past twenty years, there have been numerous instances of damage to the outer sheath of cables, the cause of which remains unknown. Surprisingly, some of these cables were not even in use at the time of the incidents. Most of the damages occurred in areas with a high frequency of lightning strikes. To address this issue, a research study is currently underway to examine the impact of direct lightning strikes on medium voltage cables and develop protective measures. As part of the study that is ongoing, we are developing a simulation model that takes into account factors such as soil ionization, lightning parameters, and moisture to mimic realistic lightning strikes on the ground. The main aim is to utilize the acquired knowledge to aid in selecting suitable cable design for future projects.
