eTool : Electric Power Generation, Transmission, and Distribution
Grounding Impedance Protective grounding systems must use proper equipment and be designed, installed, and arranged to reduce any stray voltage to a safelevel. If reenergizing occurs, the grounding impedance (resistance) must be low enough to ensure the prompt operation of protective devices (for example, fuses and breakers).
6.10 Electrical Equipment and Grounding
System grounding is the intentional connection of the neutral or one phase to earth ground, either solidly or through a resistor. Ungrounded power systems may be more prone to equipment malfunction related to transient over voltage induced damage than grounded systems.
