9. ### calculating total amperage?

Power is sqrt(3)*V*I*PF. where PF is the power factor. The PF should be around .8 for this size motor. The energy is power times time where time is in hours.

10. ### why we dont increase the PF(power factor to 1?we always keep it 0.85 is there any effect related to resonance?

I assume you're referring to power factor in the operation of power systems. In a power system the load is the customer and the power plant is the provider. The load (customer) usually demands power at a power factor of <1. This is...
