NettetDescription. The Current Measurement block measures the instantaneous current flowing in any electrical block or connection line. The Simulink ® signal output provides a signal that other Simulink blocks can use.. The power_currmeasure example uses four Current Measurement blocks to read currents in different branches of a circuit. NettetThe output is the phasor representation of the first harmonic of the instantaneous value of the probed signal. The phasor representation is a 2-signal bundle of the polar coordinates of the phasor. The polar coordinates are the magnitude and angle of the phasor in a rotating reference frame.
