When installing a star ground, what is the best approach to lower resistance and reactance?

The best approach to lower resistance and reactance when installing a star ground is to increase the number of conductors while keeping their lengths short. This is because resistance in conductors is influenced by both the material and the geometry of the conductors. By increasing the number of conductors, you effectively reduce the total resistance of the grounding connection. This is due to the fact that current has multiple paths to flow through, which decreases the overall impedance of the grounding system.

Additionally, maintaining shorter lengths for the conductors helps to minimize losses associated with resistance and reactance, as longer conductors tend to have higher resistance. Shorter conductors also reduce the effects of inductance, which can increase reactance in AC applications. Therefore, utilizing a greater number of short conductors ensures that the star ground system is both effective and reliable by providing multiple pathways for grounding, thus lowering resistance and reactance effectively.
