Answer Posted / b.murali dhara babu
speed of the Induction motor can be caliculated using the
formula N=120*f/p , N = speed of the motor , f= frequncy
of the supply , p = pairs of poles .The speed of the
induction motor is always runs at less than its
synchronous speed due to leakage flux from stator to the
rotor .If change the parameters llike f, p the motor
rated speed also changes again the new speed is less thaqn
it synchronous speed due to the leakage flux and rotor
inertia and friction .

Dear sir, In our plant have Station Transformer having capacity,i want to know, why LV side 40 - 40MVA is given? & how we can get 6.3 KV supply from tertiary(i.e. Open delta connection), Vector Group YNyn0 - yn0 +d MVA Rating 80MVA / 40 - 40MVA + 26.7MVA Voltage rating 420 (Tap range +6,to -10)81.25% /11.5KV - 11.5KV +6.3KV
