I think you mean 'three phase', not 'three face'!

Power factor is a function of the load, notthe generator. The power factor of the load can be determined from its true power (expressed in watts) divided by its apparent power (expressed in volt amperes). For a balanced load, this can be done by manipulating the following equation:

True Power = 1.732 VL IL x power factor

Where VL and ILare the line voltage and line current.

For an unbalanced load, it is rather more complicated than can be explained in this forum.

How many amps does a 18000 watt generator provide at 120 volt 3 phase service?

The equation for power in a three-phase system is given by the following equation:P = 1.732 x line voltage x line current x power factorSo, to calculate the line current, we can manipulate this equation, as follows:line current = power / (1.732 x line voltage x power factor)As you make no mention of power factor, we shall assume the power factor is 1, and we also need to assume the 230 V you quote is a line voltage, so we can calculate the value of current as follows:line current = 18 000 / (1.732 x 120 x 1) = 86.6 A


What are the advantages of using a three-phase generator compared to a single-phase generator?

A three-phase generator is more efficient and provides a more stable power output compared to a single-phase generator. It is also capable of handling heavier loads and is often used in industrial settings where high power demands are required.

How to Calculate three phase watts with unbalanced phase current?

You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.


How do you calculate 3 phase power with a power factor?

To calculate three-phase power with a power factor, you would use the formula: P = √3 x V x I x PF, where P is power in watts, V is voltage, I is current, and PF is the power factor. Multiply √3 (1.732) by the voltage, current, and power factor to determine the power in watts.


How do you convert a single phase generator to a three phase generator?

You really can't without replacing the generator end (head) with an end wound for three phase. Three phase ends are not usually made for smaller generators. Of course, once the power leaves the generator, it could be applied to a static or rotary convertor same as is used with utility power. Make sure the generator has sufficient KW to run both the load and the convertor. I agree. You can't without a converter.


What generator produce voltage or power?

First of all power = voltage* current*power factor (a constant that varies on the characteristics of the electrical system) so to generate power a generator has to a level of voltage and should be capable to handle the current demand of the load (viz electrical load like the bulb we use at home or the pump motor - everything connected to the generator by electrical wire put together).


Can you use a portable generator like the one sold at home depot along with household power to generate 3 phases of electricity?

No, a portable generator typically provides single-phase power, which is insufficient for generating three-phase electricity. While you can use multiple single-phase generators in a specific configuration to create three-phase power, it requires specialized equipment and knowledge. Most household setups do not support three-phase systems unless specifically designed for it. For three-phase power, a dedicated three-phase generator or a commercial power supply is needed.
