Use the following formula Kilowatts = I x E x 1.73 x pf/1000 where pf = power factor. If you have the access to a three phase watt meter, connect it into the circuit for a specific time interval and you will obtain a reading in kWhs.

AnswerThe above answer is only applicable to a balancedthree-phase load. If the load is unbalanced, then you need to determine the power of the three individual loads, and add them together. If you have access to wattmeters, then (in accordance with Blondel's theorem) you can use one less wattmeter than there are conductors supplying the load, to measure the total power whether balanced or unbalanced.

How you convert the value of single phase power to value of 3 phase power?

Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.


What is the difference between single phase circuit and tree phase circuit?

A single-phase circuit has one live conductor and one neutral conductor, typically used for residential applications. A three-phase circuit has three live conductors and one neutral conductor, used for higher power industrial applications due to its ability to provide a more balanced power distribution.


How do you get 347V?

347V can be obtained from a three-phase power system, where the phase-to-phase voltage is 347V. This typically involves connecting three alternating current power lines that are 120 degrees out of phase with each other to create a three-phase circuit, which results in a higher voltage output than a single-phase system.


Single phase and three phase circuit?

Yes, there is a difference between single phase and three phase circuits.


Do you need only a watt-meter in a three phase power?

To measure the power of a three-phase load, you need to use one less wattmeter than there are conductors supplying that load.

Can you use 3 phase circuit as 3 separate single phase circuit?

Yes, a 3-phase circuit can be used as three separate single-phase circuits by connecting each load to one of the phase conductors. This allows you to operate three independent single-phase loads using the same 3-phase power source. However, caution should be taken to ensure that the loads are balanced among the phases to avoid overloading any of the phases.


What circuit you can use to run three phase motor?

It must be a three phase supply service to run a three phase motor.


Difference between two phase and three phase welding machine?

Three phase uses a safety circuit away from the machine, two phases uses you as the safety circuit


How you measure power factor in three phase load by two wattmeter method?

First of all, you can only measure power factor of a three-phase load, provided that it is balanced load. The power factor can then be found by determining the cosine of the phase angle, using the following equation:tan (phase angle) = 1.732 ((P2-P1)/(P2+P1))...where P1 and P2 are the readings of the two wattmeters.


Can you power a three phase motor and a 208 motor on the same circuit?

Yes, with the proper control equipment ahead of the motors.


Is it possible to measure power factor of the balanced three-phase load by two-wattmeter method?

yes.
