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).
When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
How do you calculate the phase current when working with a 10kw 3 phase electrical motor?
To calculate the phase current of a 10kW 3-phase motor, you can divide the total power (10kW) by the square root of 3 (approx. 1.732) and then divide that result by the line-to-line voltage. The formula is: Phase Current (Amps) = Power (W) / (√3 x Line-to-Line Voltage (V)).
How long is a total eclipse of the sun?
The total phase, as seen from a given point on the Earth, is never longer than 7 minutes 30 seconds.
The total power in a 3 phase system may be measured using a single fixed wattmeterprovided the?
the system is balanced, meaning that the three phases have equal voltage magnitudes and are 120 degrees apart in phase angle.
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
In a 3-phase high voltage star-star connection 140KVA transformer and load phase voltage is 115v and frequency is 400hz what is the total load current?
Maximum load current on a 140KVA, three phase transformer when the output voltage is 115 v phase to phase is: 140kva / sqrt (3) / 115 = 703 Amps. frequency does not matter here.
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 amperage of a 3 phase transformer?
Total KVA of the transformer divided by (square root of 3 times the voltage). This will give the individual phase currents. These individual phase currents will be 120 degrees out of phase with each other.
What voltage should be used when making three phase calculations?
With a three-phase system the voltage quoted is the line-to-line voltage between any two live lines. To find the line-to-neutral voltage divide by 1.732 which is sqrt(3). The power supplied from each phase is the current times the line-to-neutral voltage (times the power factor if less than 1). To find the total power when the currents are equal, multiply by 3.
A 100 amp 3 phase power supply is good for how many total amps?
100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V x 1.73 = 83040 watts. - 3 single phase 480v (L-L voltage) heaters, 100amp. 173A x 480V = 83040 watts. - 3 single phase 277v (L-N voltage) heaters, 100amp. 300A x 277V = 83100 watts.
How is a single phase voltage generated?
The process of asingle-phase ac voltage generated from hydro-powerAnswerPower station alternators generate three-phase electricity as, for any given load, it is more economical in terms of the total volume of copper required by transmission lines, transformers, etc. Single-phase supplies are normally produced by small, portable, alternators. The difference between the two is the way in which the machines' armatures are wound. For a three-phase machine, there are three separate windings, physically displaced from each other by 120 degrees, so three phase voltages are produced which are 120 electrical degrees apart. Single-phase machines, on the other hand, have just one armature winding, and produce just one voltage.
