Three-phase power can be measured by two watt-meters method. In this method, we have two types of connections. They are star and delta connections of loads. In this electrical calculator, 3 phase power can be estimated using the star type connection.
Calculator of three-phase power by two watt-meters method
P = ( V12 * I2 * cos ( 30 + θ ) ) + ( V13 * I3 * cos ( 30 – θ ) )
- P = Three Phase Power V12 ,
- V13 = Voltage I2,
- I3 = Current
- θ = Displacement Angle
- cos = Cosine
