You can estimate the total running load by adding up the running wattages of all items to be powered. If the name plate show only amps and voltage the wattage can estimated by multiplying volts times amps to calculate watts. Amps times Volts equals Watts. The watts total divided by 1000 is kW.

Multiply the MWh figure from Step 1 by 8,760, the number of hours in a year. In this example, that would yield 87,600 MWh total annual power production. Divide the annual MWh figure from Step 2 by 1,000 to get GWh. Thus, 87,600 MWh/year equals 87.6 GWh/year.

Divide the number of watts required by the volts to determine the needed amperage. For example, a 120-watt device, requiring 1,200 volts requires 10 amps.

Just add the Power(KW) ratings of the different loads(motors, lamps, fans etc.) present in the building. This would give an approximate value of the total electrical load in the factory. You can find KW rating of a motor with HP rating by using the equation, 1HP=0.746KW.

The average cost to install a home generator is just over $3,700. Prices start as low as $400 and go as high as $9,500.

Calculate the power the motor consumes while in operation. The equation is W = AV(sqrt 3) where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.

Your electric bill is calculated by your energy usage (total watts used) multiplied by the electric rate for your home or business. Energy usage is measured in kilowatt hours (kWh). A kilowatt equals 1000 watts. A kilowatt hour equals 1000 watts for 1 hour.

The load factor percentage is derived by dividing the total kilowatt-hours (kWh) consumed in a designated period by the product of the maximum demand in kilowatts (kW) and the number of hours in the period. In the example below, the monthly kWh consumption is 36,000 and the peak demand is 100 kW.

So it seems you want to convert electrical energy into mechanical energy. Now considering that you want to lift mass of 100 kg through height of 10meter in 1 minute. Hence, mechanical energy required is= 100*9.81*10 = 9810 joule. Pi (electrical power input) = 10900 / 60 = 181.67 Watt.

Calculate power rating in kilovolts-amperes, or "KVA," when you know voltage and current rating. Use the formula: P(KVA) = VA/1000 where P(KVA) is power in KVA, V is voltage and A is current in amperes. For example, if V is 120 volts and A is 10 amperes, P(KVA) = VA/1000 = (120)(10)/1000 = 1.2 KVA.

So to find the current drawn, simply divide the power by the operating voltage. In the United States, most household appliances work at 110 Volts. So the calculation is divide the Wattage by 110. For example: A 40 Watts bulb draws 0.36 Amps to operate.
