Answer Posted / dileep kumar
emf induced in the rotor conductors is dynamically induced emfs.cndotion for dynamically induced emf is there z relative motion between flux and rotor conductors. if induction motor is rotating at shynchronous speed , then relative velocity is zero & no emf production & torque is proportional to the square of the induced voltage so no torque which can turn or twist the rotor is zefo thats why induction motor never rotate at synchronous speed

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
