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...

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.

This study was done to determine the possibility of having insulation breakdown of the underground cable either by direct stroke or by induction. The simulation was performed using Alternative Transient Program version of the Electromagnetic Transients Program (ATP-EMTP) software to determine whether the induced voltage due to lightning can cause any insulation breakdown. A network system consisting of 33kV Cu/XLPE/CWS/PVC/HDPE insulated armoured Polyvinyl Chloride (PVC) sheathed cable rated was modelled.
