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.
