Orta Gerilim şebekelerin büyümesi ile enerji kablolarının kullanımı gün geçtikçe yaygınlaşmaktadır. Kullanılan kablolar hem dış etkilere karşı mukavemeti arttırmak hem de topraklama amacıyla zırh ve ekran katmanlarına sahiplerdir. Bu katmanların kablonun her iki ucunda topraklaması için literatürde farklı yöntemler bulunmaktadır. Kablo topraklaması için seçilen yönteme göre zırh ve ekran katmanlarında gerilim veya akım endüklenir. Endüklenen bu gerilim veya akım da kabloların hem güvenli işletilmesini hem de akım taşıma kapasitesini doğrudan etkilemektedir. Bu makalede konuyla ilgili teori incelenerek, güç kabloları analiz yazılımında gerçekleştirilen benzetim çalışmasıyla XLPE 240 mm2 bakır iletken için oluşan değerler teyit edilmiştir.

The use of energy cables is getting widespread day by day. These cables have armor and screen layers for grounding purposes. There are different methods in the literature for earthing of these layers. Voltage or current is induced in the armor and screen layers according to the method used. This induced voltage or current directly affects both the safe operation and current carrying capacity of the cables. In this article, the theory on the subject has been examined and confirmed by the simulation study performed in power cables analysis software.
