Three-phase power is used primarily in power distribution systems such as the power systems that power homes and businesses. Real Power. This is because they offer more control in terms of how much power is being sent to your equipment, and in some cases, this may allow you to use less equipment. The power P in kilowatts (kW) is equal to 3 times the power factor PF times the phase current I in amps (A), times the line to neutral RMS voltage V L-N in volts (V) divided by 1000: P (kW) = 3 × PF × I (A) × V L-N (V) / 1000. cos φ = cosinus phi (without unit), P=√3*U*I*cosφ P1=V*I1*cosφ1 3 phase systems are far more streamlined than single or even dual phase systems, which means they use less power, but produce the same results.. For a tutorial on three phase calculations, please see: Three Phase Current - Simple Calculation. A three-phase system may be arranged in delta (â) or star (Y) (also denoted as wye in some areas). Often us engineers get so bogged down in equations, using software, producing drawings and writing specifications that this becomes the sole focus. Smart Energy User â Calculating What It Costs to Run a Motor Doing a Rough Calculation â If the load on a motor is fairly consistent, and if you have access to a voltmeter and clip-on ammeter, it is easy to arrive at rough kVa and kWh figures.
