Low-Impedance Grounding in Power Systems

To eliminate the need for reactors or resistors in the system neutral

To limit the fault current and permit selective protective relaying (correct)

To increase the fault current to match the power system impedances

To increase the line-to-neutral equipment insulation requirements

In the primary of the delta-wye supply transformer

In the secondary of the wye-delta supply transformer

In the neutral of the delta-wye supply transformer (correct)

In the neutral of the wye-delta supply transformer

It increases the fault current rating

It is not affected by the ground faults (correct)

It reduces the cost of the overall system

It provides a higher level of protection
