Description

The Current and Voltage Sensor (Three-Phase) block measures the voltage and current of a three-phase electrical node.

Note

You must connect the Current and Voltage 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.

Ports

Output

V — Voltage

physical signal

Three-element physical signal vector output port associated with the a-, b-, and c-phase voltages.

I — Current

physical signal

Three-element physical signal vector output port associated with the a-, b-, and c-phase currents.

Conserving

~1 — Three-phase voltage and current

electrical

Expandable three-phase electrical conserving port 1 associated with three-phase voltage and current.

~2 — Three-phase voltage and current

electrical

Expandable three-phase electrical conserving port 2 associated with three-phase voltage and current.

Parameters

Modeling option — Whether to model composite or expanded three-phase ports

Composite three-phase ports (default) | Expanded three-phase ports

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.

Voltage measurement type — Voltage measurement type

phase-to-phase voltage (default) | phase-to-ground voltage

Type of voltage measurement.

Measurement output unit — Measurement system

Per unit (default) | SI

System of units for output current and voltage measurements.

Nominal power — Nominal power

100e6 V*A (default)

Nominal power.

Dependencies

To enable this parameter, set Measurement output unit to Per unit.

Nominal voltage (phase-to-phase RMS) — Nominal voltage

24e3 V (default)

Nominal phase-to-phase root-mean-square (RMS) voltage.

Dependencies

To enable this parameter, set Measurement output unit to Per unit.
