Grounding High Voltage Lines

Grounding High Voltage Lines. Understanding these principles will provide the correct tools to design a grounding system applicable to utility networks and industrial plant distribution. National grid owns the high voltage electricity transmission system in england and wales and operates the system throughout great britain at 275,000 and 400,000 volts (275kv and 400kv).

This to ensure that safety issues are taken care of without constructing an over dimensioned, and more expensive than necessary, system. The distance between the "dead" line and the parallel energized line. Electricity can flash over a gap, so any equipment or a person at some distance from the power lines can still be in danger.
