WebThe line current is calculated based on the expected real power requirement and phase angle. The following equations show the calculation of line current: Single-Phase Circuits ×cosθ = V P I L where, I L = Line current in amperes P = Real power, in kW V = Voltage, RMS—in kV to match power units θ = Phase angle between voltage and current WebPower requirement will change only a small amount. The ‘Productive Power’ is the power that is transferred from electrical energy to some other form of energy (i.e. such as heat energy or mechanical energy). The apparent power is always in always in excess of the productive power for inductive loads and is dependent on the type of machine ...
