Feeder current
Feeder current
(OP)
Hi,
I have a 3 electrical boards (3phase 380/230) to feed from a substation.
Electrical Board 1:
S=46KVA
Electrical Board 2:
S=46KVA
Electrical Board 3:
S=120KVA
The current that each eletrical board will "consume" is calculated by:
I = S/(sqrt 3 *400)
Is this correct?

Possibly 400/230V?????

RE: Feeder current
The voltage level is 230/400.
it comes from a feeder located in a private substation.

RE: Feeder current
(KVA x 1000) / (230V x 3) = A
