Targeted Mitigation Improves Reliability

摘要

LIGHTNING, OR THE RELATED CAUSE OF EQUIPMENT FAILURE AFTER A LIGHTNING STORM, has been found to be the cause of many distribution-system interruptions. Such is the case for National Grid (serving portions of New York, Massachusetts, New Hampshire and Rhode Island), which has developed new methods to view its reliability performance in combination with geographic information system (GIS) and lightning-performance data to mitigate future lightning interruptions where it will achieve the most reliability improvement. National Grid is also mining its existing data for new information to find areas where it can improve standards or construction practices before major lightning-caused impacts occur.
