Connect phases of three-phase system to electrical conserving port
Simscape / Electrical / Connectors & References
The Neutral Port (Three-Phase) block connects the phases of a three-phase system to an electrical conserving port.
If you do not need to connect the neutral port to other blocks, use a Floating Neutral (Three-Phase) block instead. If you want to ground the neutral port, use a Grounded Neutral (Three-Phase) block.
Parasitic ground conductance— Parasitic ground conductance
Parasitic conductance to ground. A nonzero value is required for the simulation of some circuit topologies.
