Data: 66KV power cable, 3 phase, short circuit current 40KA, at a lod of 50 MVA.
Question 1. : In the cable sizing up process, is the cross section area meant for one cable feedng per phase or or all three pahses? Lets say the cable size come out to be 288 sq mm..does this represent a single cable (3 core+Earth) with total cross section area?
Question.2: What about the continuous current rating given in the catalogue? Will it be the total current carried for all three phases or each phase will carry that current to the load?
Thanks
