Grounded Neutral (Three-Phase)

Connect phases of three-phase system to electrical reference

  • Grounded Neutral (Three-Phase) block

Simscape / Electrical / Connectors & References


The Grounded Neutral (Three-Phase) block connects the phases of a three-phase system to ground.


If you want to connect the neutral point of the three-phase system to other blocks, use the Neutral Port (Three-Phase) block instead. If you want to create a floating neutral point, use the Floating Neutral (Three-Phase) block.

Expandable composite (a,b, c) three-phase port.

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.
