yes
I think you mean a 240 V to 110 V (volts, not watts) transformer! Providing your power tool is rated at 110 V, the answer is yes, because its power rating of 1500 W is well within the capacity of a 3-kV.A transformer.
If the transformer is three phase the calculation is I = 30,000 / 1.73 E. If the transformer is single phase the calculation is I = 30,000 / E. (Where I = current and E = secondary voltage) It is important to note the voltage in the first formula is line to line (typically how it is specified in three phase power systems), and the second formula it is line to neutral.
21.4 amps, 2100 wattsManoj
To calculate an answer a voltage must be stated.
200V / 240V 5 / 6
230 v 6 amps is 1380 VA which equals about 1 kW, so a 3 kW motor implies it's a 3 phase motor. It would turn over on a single phase supply in whatever direction it was first spun in, but the performance would be poor and the motor or generator could get damaged.
Writing VA is just another way of writing watts, as watts = volts x amps, so 3kva means 3000 watts. Divide by 210, and the answer is 100/7 = 14 to the nearest whole number, but you could make it 15 to be sure, then you would have a 5 by 3 array.
The number of solar panels needed to generate 3 kVA of electricity depends on the efficiency of the panels and the amount of sunlight they receive. On average, a 300-watt solar panel can produce around 0.3 kW of electricity. Therefore, you would need approximately 10 solar panels to generate 3 kVA of electricity.
For USA, Canada and countries running a 60 Hz supply service.As you asked this question here the best advice anyone should give you is to call a licensed electrician to install a new 120 volt branch circuit for new outlets for you. In the United States 240 volts is produced by two 120 volt hot wires 180 degrees out of phase. Added together the voltage difference is 240 volts. To get only 120 volts one of the hot wires needs to be replaced with a neutral wire.That would make the voltage difference to the neutral 120 volts. (There may or may not be an existing neutral wire running to the outlet. Whether there is one depends on the purpose for which the 240 volt outlet was originally installed.)It is often not worthwhile to change the existing 240 volt outlet - it is often best just to leave it there to power 240 volt appliances.A licensed electrician would know how to check this for you and would advise the best action for you to take. He would use the correct size of wire to supply the current required by the 110 - 120 volt appliances you want to use and connect it to the correct sizes of circuit breakers on the main panel and also a GFCI safety device to protect users from electrocution if the room is likely to be damp or have water spray or wet floors, walls or ceiling, such as a laundry room or a kitchen. All this is necessary to comply with the latest Wiring Codes in your locality. (Town/State.)Then you would be able to use a 110 - 120 volt appliances safely in the room in question.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
