About this document
Short Circuit Capacity Calculation for Cables by Abdullah Al Asik is a document available to read on EtoBox.
The document calculates the short circuit capacity of a 1x240 mm2 33 kV underground XLPE copper cable for durations of 1 second and 3 seconds. For a 1 second duration, the cable conductor can withstand 34.3 kA, the metallic screen 10.91 kA, and the armour 20.62 kA, for a total earth fault current of 31.53 kA. The calculations are shown for each component using the cable specifications and formulas involving cross-sectional area, temperature factors, and the square root of time.
