Why are the HV motors are connected in star connection?
Answer Posted / pjs raju
In Delta connected winding full line voltage(equal to phase
voltage) is applied on each phase so stator current would
be higher (root 3 times more than star connections) SO
In Star connected HT Motors , stator applied phase voltage
reduced by root 3 times so Current would be reduced and
motor is better protected and low consumption losses.
