Sheet # 6 3-Phase Induction Motor (Power Calculations)

SC MVA is the power available at a bolted three phase fault. Bolted means all three phases con-nected together with no added impedance. X/R is the ratio of reactance to resistance in the supply. SC MVA and X/ R may need to be derived from other data. Short-circuit current (I SC) is sometimes supplied by the power company rather than SC MVA. This current is the current in one phase of a three

Sheet # 6 3-Phase Induction Motor (Power Calculations)

21/03/2011 · Supply calculations for 3 phase motor. Discussion in 'Commercial Electrical Talk' started by Dunc, Mar 21, Based on this i understand it's a 7.5kW motor with a power factor of 0.88. So i would you calculate the load per phase as being the following: 7500/(400V*root 3*0.88)=12.3A per phase. I would then assume that a 16A supply on a C type breaker is necessary and based on a run …
