This is in relation to the question on how much hydroelectricity can be generated. so basically if I can generate 1 hp, what should that be in VoltAmpere?
Thanks

1 hp = 746 VA. So, u will generate 746 watts in 1 hp.

Since you asked for VA and not watts this implies that a power factor may be involved. VA = Watt = 1/746 HP only if voltage and current are in phase. The power factor is the cosine of the phase difference between the voltage and current, and that depends on the load being driven. Also, if 1 HP is the mechanical power input to the generator, you must also consider the efficiency of the machine. Only with 100% efficiency and unity power factor does 1 HP produce 746 VA.

746 watts equals 1 hp but you need about 20% more to get 1 hp from a motor..
