โ 12y agoThe following formula is used to find amperes when kilowatts are shown.
kw x 1000/1.73 x E x pf.
The term pf is the power factor value usually using a value of .9.
18000 watts is equal to 18 kWs.
18 x 1000/1.73 x 240 x .9 = 18000/374 = 48 amps.

โ 12y agoTo calculate the amperage, first convert the 18000 watts to VA by multiplying by โ3 (since it's a 3-phase system), which equals 31103.2 VA. Then, divide the VA by the voltage in volts to get the amperage, yielding approximately 129.6 Amps.
A 18000 watt generator supplying power at 240 volts would supply 75 amps (18000 watts รท 240 volts = 75 amps).
Answer for UK, Europe and countries running a 50 Hz supply service.A farm that takes a 700-amp supply on 3-phase 415 volts is a big farm drawing 500 kVA so it really needs a 750 kVA generator that would be expected to use 60-70 gallons of diesel per hour. It should be noted that 3 phase 415 volts is a 50 Hertz generated supply.At lower voltages the power drawn would be less, but the answer is independent of the supply frequency.Answer for countries running a 60 Hz supply service.A farm that takes a 700-amp supply on 3-phase 208 volts is a farm drawing 250 kVA that needs a 300-350 kVA generator. It would be expected to use 30-40 gallons of diesel per hour.
To find the amperage of a generator, you can use the formula: Amps = Watts / Volts. Assuming a standard voltage of 120V for household generators, you can calculate the amperage as: 8500 Watts / 120 Volts = 70.83 Amps.
You can use a transformer to step down the voltage from 400 volts three phase to 230 volts single phase. Connect one of the phases and the neutral of the three phase supply to the transformer primary winding and then connect the secondary winding to get the desired 230 volts single phase supply.
The typical single phase voltage in Canada is 120 volts.

How much current equipments are drawing from three phases (combined or individual) is called three phase load and how much supply we are getting from source is called three phase supply. Ex. In INDIA single phase supply is 220 volt ac with neutral. So in three phase supply all RYB phases should be 220 volts ac with neutral individually. If we calculate with phase to phase than it shoulb be 415 volts ac.

The process of obtaining 220 volts from 380 volts is quite simple. 380 volts is a three phase four wire system voltage. The 220 volts is obtained by taking the sq. root of 3 which equals 1.73 and dividing it into the phase voltage. 380/1.73 = 220 volts. This holds true with any three phase four wire voltage system. 208/1.73 = 120 volts, 415/1.73 = 230 volts, 480/1.73 = 277 volts and 600/1.73 = 347 volts. This lower voltage is present on any of the three phase legs of the three phase system to the neutral which is grounded on a wye connection.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
No, you will not obtain 230 volts. From a wye connected three phase 480 volt supply, 277 volts can be obtained from one phase leg and the neutral on the wye connection. 480 volts/1.73 (sq. root of 3) = 277 volts.
No, you can not you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 Hz supply. They are two different electrical systems.
