On average you use 27.54 kW in 24 hours or 1.147 kW average. Reality is that some hours will be considerably more and some considerably less. Based on 0.83 power factor, at average draw your KVA requirement is 1.147 kW/ 0.83 = 1.38 kVA. Your service (wiring meter, etc) is sized for a maximum draw of 25 kVA.
For example 1 amp * 110 volts/0.6 = 183 VA. Converting Amps to KVA (voltage fixed) The conversion of Amps to KVA is governed by the equation KVA = Amps · Volts/ (1000·PF) For example 100 amp * 110 volts/ (1000*0.6) = 18.3 KVA. Converting VA to Volts (current fixed) The conversion of VA to Volts is governed by the equation Volts = VA·PF/Amps.
10-12-2009, 06:16 AM. Re: Convert volts/amps into kilowatt hours. Originally posted by Unregistered View Post. after Converting 8 amp 12 volts for 5 days is the answer in watts or watt hrs. It depends. If the load is constant, the power is 96 W. If it is drawn for 5 days, on a 24 h basis, the energy consumed is 96W x 5 days x 24 h/day = 11520 Wh.
120 V: 62.5 A. or 240 V: 31.25 A. or 480 V: 15.6 A. Each alone would be 7500 W. If you run loads at different voltages, multiply each voltage by the load in amps at that voltage, add the wattages. Must be less than 7500 W. Flag. Post any conversion related questions and discussions here.
So if you take the total kw's you need, divide it by 3(3 phases) multiply that by 1000(turn it into watts) and divide that by the voltage(120?) that will give you your required amps per phase. The whole load should be evenly distributed over the 3 phases as uneven loads can cause higher bills.
Re: how to convert amps into kwh usage can any body help me to get the right generator for my crusher plant , i had in section A ( 9 morors , total of 240kw, total of 490amp, volt 380, 3 phas.) section B ( 14 motors ,total 510kw,967amp,volt 380,3phas) thanks for you.

I have a client that is telling me he is ordering a machine that uses 450kW 3 phase. According to my calculations that means he needs a cable big enough to allow for current draw of 783 amps per phase! Is this correct? Or do I need to divide 783 by 3 to get a current rating for each phase? (assume 415 volts, 3 phase, power factor 0.8). Please ...

converting amps to kwh requires multiple equasions, for example i will show the process for converting the amps used by a 100 watt bulb in a 115/120 volt powered circuit. E=IxR states that volts are equivilent to amps X watts So inversly volts divided by watts = amps in this case 120 volts divided by 100 watts =1.2 amps
