HT Cable size dependson fault level to be withstood and its duration..
If you take XLPE, HT Cable of ALU conductor,
condiering 350MVA for 1 sec *(18.37kA), min. C/A will be found out by Area(A) = (Short ckt current (kA)*Square root of Time)/k
k is constant = 0.094 for XLPE ALu conductor.
This will give you min. size required for HT system (11/22/33/6.6/3.3kV)
Choose nearest standard higher size for HT Cable..
primary 3*240 sqmm AL cable
