One horsepower is equal to 746 watts.

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.
VA or KVA or MVA
The kV.A (not 'kva') rating is the total apparent power of the machine. So a 75 kV.A machine is 25 kV.A per phase.
Keeping in mind that there is 746watts per Hp should lead you to the answer. For ex. Power(in KVA) = Voltage (1.73)x CurrentTherefore, if you know the voltage, typically 480Vac, then 150(746) = 480 (1.73) x I150Hp(746w/hp) = Voltage x Current= about 135 amps current. Now you also need to factor in the Power Factor (PF) of the load (150Hp). The power factor depends on the type of load. A motor is mostly Inductive, a heater, or lighting bank is resistive, and capacitive loads aren't that common. Your question is a bit vague. If you'd like to rephrase your answer or send it directly to me, I'd be glad to assist you further. You might also want to check out a site called "Mike Holt's Code Forum'. If you're an EE student, I'm sure the path to your solution is in one of your 'Power' books.
kva*cos(phase angle)
1HP = 746 watts 15 HP = 11190 watts = 11.19 kW You would need a generator of at least 13kW. UPS Distributor for 15 Years.

Depends on the kva rating of the devices to be tested using a transformer.
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.

transformer action doesn't depend on power factor that is why we indicate its rating in KVA

If a device doesn't give its power rating in kVA (or VA), then it can be calculated pretty easily: (volt-amperes) VA = V (voltage) x A (maximum amperage) (kilovolt-amperes) kVA = VA (volt-amperes) / 1000
