400kw, 3.3Kv motor want to fix 1000km away from substation.
What is full load current? and what is the cable size for
motor? I amp expecting answer and advice from your side..
thanks...

Answer Posted / pillay

i agree with mr prakash,1000KM is a riduculous distance for
practical 400 kw load. any way the usual power formulas will
give you the full load current , the type of starting will
give you an idea of the initial current and the cable
formulas will
guide you about the voltage drops along the distance.Than you
can pick the correct cable size and the cost, may be you
would decide to built a power station.
