This 3-phase power calculator determines the active, apparent, and reactive power from known RMS voltage, current, and power factor for a symmetrical three-phase system with a balanced load. Example: Three equal inductive loads with a power factor 0.68 are connected in star to a 400 V (line...
The Power Measurement (Three-Phase) block measures the real and reactive power of an element in a three-phase network.
The results showed that three-phase foams are governed by an equation depending on pressure, temperature, foam specific volume, foam specific incompressible volume and moles of gas. This relation, P ( V s V si ) = N g RT , will be, in addition way, a function of the solid content ...
It is reported that the vibrational part plays an important role in obtaining the gas, liquid and solid phases and the correct phase transitions. A method of combining the two lowest order approximations (single site, two-site) in the cluster variation method is suggested in describing the ...
Total active power is given by [tex]P=3P_1=3\sqrt{3}U_RI_R\cos\angle(\underline{U_L}\underline{I_R})[/tex] To use this equation, we need to draw phase diagram and find [itex]\angle(\underline{U_L}\underline{I_R})[/itex] which is [itex]\approx 41.4^{o}[/itex]. Ap...
For three-winding transformers (three-phase), the coupling between different windings in each phase is identical. Consider phase A first. This equation represents the inductance matrix for primary and (first and second) secondary windings and the relationship between the parameters in the electrical ...

other end, when ABC are at position +Ntap and abc are at position −Ntap, the output voltages abc are leading input voltages ABC by 60 degrees. For intermediate positions, the phase shift ψ is given by the equation on the figure. This equation assumes that all tap are...
These samples are phase corrected and passed on to the foreground process, which uses the number of samples (sample count) to calculate phase active and reactive powers by the formulas in Equation 2. 10 Implementation of a Three-Phase Electronic Watt-Hour Meter Using the SLAA577G – January ...
