Using 11000V/433V,3 ph,50Hz,500 KVA, what is the maximum
capacity of motor in KW that can be connected and started at
a single moment? Also explain about any calculations and
formulas used in deriving the same.

Answer Posted / dinesh kannan
Since the motor is connected in 433V side , we consider
powerfactor 0.8.so maximum connected capacity of motor is
500*0.8, but we have to run the motor in single start
there are so many methods are there to start the motor like
DOL, star delta starters based on the starter and starting
current of motor we deside the maimun rating of motor( to
start the motor, minimum 70% of voltage is required
