Three-phase systems are prevalent in many power distribution systems. This is because 3-phase systems have built in efficiencies for high power transmission systems. The word 3-phase means the system has three separate lines, spaced 120 degrees apart, where each line carries the identical voltage....
Three-phase circuits distribute electrical power along multiple conductors in the same power line. The current waveform of each conductor is offset in time from the others. This allows more power to be transmitted on one line at a lower voltage, increasing efficiency without sacrificing safety. For...
The currentIin amps is equal to the powerPin watts divided by the product of the voltageVand the power factorPF. You can calculate the power factor using apower factor calculatorif needed. Three-Phase AC Current Formula To calculate the current for three-phase AC circuits, you need to use...

of three phase-power. In an ideal system, each of the phases within the respective cable has a phase angle which is generally 120 degrees apart from the other phases. Accordingly, the total power flowing through the three cables to a three-phase load (or from a three-phase generator) is...
Application of this method deduces the transmission line modeling of three-phase power transmission line. Then calculation was made with such TLM method in actual examples. The obtained results are similar to those with other methods. It proved that this method is correct and can be used in ...

You can calculate kilo-volt-amps (KVA) from three-phase kilowatt (KW) by following a formula. This formula can be used for information regarding industrial motors and home emergency generators, provided you know the power factor. Alternatively, the power factor can be measured by finding the di...
Figure 1: A phase leg of three-phase voltage source converter Total converter losses can be calculated by multiplying it by three. If i(t) > 0, T1 and D2 inFigure 1are operational. The current waveforms for T1 and D2 can be seen inFigure 2andFigure 3respectively. Th...
