Lightning effects on underground distribution cable using alternative transient program

Underground cable is commonly used in situation where power need to be transmitted across river or sea or through heavily populated areas. Even though underground cables are not directly exposed to hazard, lightning can induce a potential on the insulation of the underground cable. About 80% of the...
