Current Sensor (Three-Phase)

Ideal three-phase current measurement

  • Current Sensor (Three-Phase) block

Simscape / Electrical / Sensors & Transducers


The Current Sensor (Three-Phase) block represents an ideal three-phase current sensor. The block measures each of the three currents flowing from port ~1 to port ~2 and outputs a single three-element, physical signal vector. Each element of the physical signal output vector is proportional to the current in its respective phase.


You must connect the Current Sensor (Three-Phase) block in series with a three-phase element. For more information on how to use this block, see Build and Simulate Composite and Expanded Three-Phase Models.

Whether to model composite or expanded three-phase ports.

Composite three-phase ports represent three individual electrical conserving ports with a single block port. You can use composite three-phase ports to build models that correspond to single-line diagrams of three-phase electrical systems.

Expanded three-phase ports represent the individual phases of a three-phase system using three separate electrical conserving ports.
