In any Industry, voltage level either 3.3kV or 6.6KV its
not chose the motor ratings.voltage level in any industry
depend upon total load of industry.firstly total load of
industry consideration & after voltage level consider.

Answer / kunal

for cost consideration of motor: It is tradeoff.. now if
high voltage rating is selected less current will flow for
same load . this will save costs on copper but at the same
time cost of insulation will increase. .....if lower voltage
is chosen then higher currents will result for same load. so
higher cost of copper but reduced cost of insulation.

for consideration of voltage for industry depends on the
load. and if heavy loads are present usually higher volatges
are chosen as losses due to current are far more.

MW rated motors will always be run on higher voltages.
higher the better.

Answer / veena

To choose the voltage level for any Load two factors has to
be considered one is the Total load and the distance of
transmission line .There is a formula to calculate the
economic transmission voltage

Answer / rocks

6.6kv line.it also depend on the rating ot the motor that
is if high motor rating the vtg drop is siginifently more
than low motor rating.hence 606kv line is morepreffered in
industry
