      Jun 17, 2002 · Istart = 16.4 KVA = 71.30 amp.23KV. Irun= 12 amp. Inrush = 71.30 amp start = 5.9 times running current. 12 amp run. So if we size the wire for 1% voltage drop on running, we will have about a 6% voltage drop on starting. If this 6% voltage drop is added to the generator recovery voltage drop of 5%, the total overall voltage drop will be about 11%.
