Description

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. To open this example, at the MATLAB^® Command Window, enter power_currmeasure.

Ports

Output

i — Output

scalar

Simulink signal associated with the instantaneous current flowing in any block or connection line.

Conserving

+ — Positive terminal

specialized electrical

Specialized electrical conserving port associated with the positive terminal of the Current Measurement block.

- — Negative terminal

specialized electrical

Specialized electrical conserving port associated with the negative terminal of the Current Measurement block.

Parameters

Output signal — Output signal

Complex (default) | Real-Imag | Magnitude-Angle | Magnitude

Format of the output signal to use when you use the block in a phasor simulation.

Set this parameter to Complex to output the measured current as a complex value. The output is a complex signal.

Set this parameter to Real-Imag to output the real and imaginary parts of the measured current. The output is a vector of two elements.

Set this parameter to Magnitude-Angle to output the magnitude and angle of the measured current. The output is a vector of two elements.

Set this parameter to Magnitude to output the magnitude of the measured current. The output is a scalar value.

Dependencies

To enable this parameter, in the powergui block, set the Simulation type parameter to Phasor or Discrete Phasor.
