Hey! I hope someone can tell me and help me out with a simple task. I need to calculate cable sizing from substation feeder to user/client feeder and choose a vaccum switch for the input feeder(user/client). The output feeder is a 6kV,630 A, 31,5kA; from a substation 3 phase AC, 50Hz, 6,3 kV, 4000A, 31,5 kA/ 3s. Need to find out what kind of vaccum switch the user/client feeder should need. And the cable sizing (cable lenght about 2km). Can someone tell me what i need to calculate and maybe help with the calculations? Thanks!
P.S The end user should have not less than 4 MW. There is 2 outgoing feeders and incoming (user/client) feeders. The second one i guess is the reserve? I hope someone can help a student out! Thanks!
