What happens to the neutral potential when additional grounding is installed?

When additional grounding is installed, the neutral potential typically decreases. Grounding serves as a pathway for electrical current to safely return to the earth, which stabilizes and reduces the potential difference in the electrical system. This added grounding provides a reference point that can absorb excess voltage, thereby lowering the neutral potential. Proper grounding also enhances the overall safety and reliability of the electrical system by minimizing the risk of voltage fluctuations that could lead to equipment malfunction or hazards. Thus, the installation of additional grounding effectively helps in maintaining a more stable and lower neutral potential.
