Good Morning everyone Lloyd here working in Iraq designing a 11kv/400v looped system 4mw with generator capacity to be 150% of calculated load, so I design for a 6mw system, with Xlpe Medium voltage cable copper cable underground system with a loop of 4000 meters so being annular the Cmil calc should be half distance for loop
2 x 12.9 x6560'x 393.65amps x .866/275vd
= 209,806.5292 Cmil there seems to be something wrong with this calc.
could you take a look for me I'm too close to the forest to see the trees. K=12.0 sq.rt of 3= 2x.866
distance to load in ft.=6560' and max vd=275v
oh and greetings from Kirkuk, iraq
