12HP is approximately 10.8 KVA. You would want to use a 15KVA transformer to supply this motor.
KW = HP * .75
KVA = KW * 1.2
(These formulas are approximate)
1 HP = 0.9325 kVA 1 KVA = 1/0.9325 HP
0 - 1000. KVA times a power factor gives you kilowatts, 1000 x watts. If the power factor is 0, then o watts make up your one kVA; if the power factor is 1, then 1000 watts make up your one kVA. Typical power factor is in the range of .8 to 1.
a VA is basically equivalent to a watt for most purposes so a KVA being 1000 VA, a KVA is basically 1000 W.However, 1 KVA = 1KW only holds true for resistive loads. If an AC power supply is running a motor or other very inductive load, KVA can be significantly higher than the power being used by the motor.The theory and mathematics of inductive loads are too complex to describe here but knowledge of inductive loads on AC supplies is one of the fundamentals of electrical engineering
1 tone = 1540 Watts=1.540 KW. whereas 1 KW=1.25 KVA. I think you have got the answer.
The motor takes 4 qts, the tranny takes 1 qt and the primary takes 1 qt
It depends on the power factor. If the PF = 1, then you need 75kVA. In general, kVA needed = 75kW/PF.
1000 VA = 1 kva
1)may be voltmeter or clipon meter will be connected across the winding. 2)or in motor winding we must find amp current and aramture resistance nd then find the ratings 3)formula is rated kva of motor*1000/base kva for transmission line.
1000 VA = 1 kva
For a purely resistive load with a unity power factor, 9.41 kVA would equal 9.41 kW. However some equipment such as a motor will have a power factor less than 1. If the power factor is 0.8 then 9.41 kVA would equal 9.41 x 0.8 kW.

3415 BTU = 1 kva The PDF uses kilowatt but they should be close enough...

For normal power factors (pf=80%), you have 0.8 kW for every kva. In general however, kW = pf x kVA. Where pf is the power factor, it is the cosine of the angular difference between the voltage and the current of a circuit in alternating current circuits.
