An electro-magnetic transient (EMT) analysis on a 132 kV rated Cu/XLPE/SCW/MDPE cable system and its related networks

For the past few decades, underground cables have been extensively used to replace overhead line system which is prone to damages due to environmental phenomena. Given the wide range of advantages it offers, there is also a need to investigate whether or not lightning transient can cause underground...

Electronics Nuclear engineering For the past few decades, underground cables have been extensively used to replace overhead line system which is prone to damages due to environmental phenomena.
