A sinusoidal current source in time-domain corresponds to an applied current phasor i in phasor analysis. In the SignalCurrent component, the effective (or rms) value I and the phase angle phase of the applied current phasor are not forced to be constant values. Hence, these values are specified by input signals.
Attention!!!
To ensure that the phasor domain-based model works in a quasi-stationary
mode, both rms value and phase angle may alter
only very slowly in comparison with both the nominal frequency
f=ω/(2π) and the dominant time constant of the
phasor domain-based model.
