What method can be used to lower neutral potential?

The correct method to lower neutral potential involves the installation of more grounds in various locations. This approach effectively enhances the grounding system of an electrical installation, providing additional paths for electrical currents to safely dissipate into the ground. By improving the grounding system, you help to stabilize the neutral point in a circuit, which can subsequent reduce neutral potential. This is particularly important in systems where imbalances and faults may occur, as it helps ensure that the currents balance more effectively, reducing the likelihood of issues such as voltage fluctuations.

While increasing wire gauge, reducing circuit load, or using higher voltage ratings might seem relevant to electrical systems, they do not specifically address the stabilization of the neutral potential in the same manner that strategically placing grounds does. Increasing wire gauge is primarily concerned with the resistance of the conductor, reducing load deals more with managing the overall performance of a circuit, and higher voltage ratings are about accommodating more voltage without insulation breakdown, rather than addressing neutral issues.
