Power can be calculated in each individual phase and summed together. If the voltage is supplied L-N in RMS: P = V*I. Note this will give the same answer as calculating balanced three phase power from the equation P = V*I*sqrt(3)

Will the two-wattmeter method work for all three-phase loads eg unbalanced loads inductive loads capacitive loads and delta-connected loads?

Blondel's Theorem tells us that, to measure the total power of a three-phase load (balanced or unbalanced), we can use one less wattmeter than there are conductors supplying that load.So the two-wattmeter method will work for anythree-phase load, provided there are only threeconductors supplying that load, e.g. three-wire delta or three-wire star (wye).Bear in mind that wattmeter's read true power (expressed in watts) and ignores the reactive power of inductors and capacitors.


How do you calculate the watts of LED and energy saver lamp?

To calculate watts you need two of the three: Voltage (V), Current (A) and Resistance (ohm). Power (Watts) = (V^2) / R = (I^2)R = VI


How do you convert hp to amp?

HP/.00134= Watts Then Watts divided by Volts = AMPS For expample. a .75 HP electric motor running on 220VAC uses 2.544 amps .75 / .00134 = 559.7015 Watts then 559.7015 / 220 = 2.544


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.

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 many watts is 4.75 amp refrigerator starting watts?

To calculate starting watts, you would typically need to multiply the amps by the voltage. Assuming the voltage is 120V, the starting watts for a 4.75 amp refrigerator would be approximately 570 watts (4.75 amps x 120 volts = 570 watts).


How do you calculate watts to amps?

The most basic calculation is volts multiplied by amps of a circuit for a single phase load.


How do I calculate the watts used by a service panel using the amps of the three phases do I sum the current and multiply by the voltage or do I average the 3 phases' current x V x 1.73?

To calculate the total power in watts used by a service panel with three-phase power, you would multiply the average current for each phase by the voltage and by the square root of 3 (√3 or approximately 1.73). This accounts for the fact that power in a three-phase system involves the line-to-line voltage and the square root of 3 relationship. So, the formula for total power (in watts) would be P = (Iavg x V x √3).
