Why do you need a lightning shielding system?Although lightning shielding systems cannot guarantee complete safety from strikes, the presence of a comprehensive solution for lightning and surge protection can dramatically reduce the effect of strikes on and near substations. To understand why a shielding system is needed, it is important to understand the risks. 1.
How can a single air terminal protect a substation?Here, a single air terminal strategically placed on a substation can protect a large area without requiring shielding wires. Active protection can respond dynamically to the presence of lightning downward stepped leaders—the first indication of an approaching strike—and create charged-up streamers that attract the strike.
Can a substation react to a lightning strike?Substations generally rely on passive shielding systems to manage the millions of added volts a strike can generate. While these systems can divert the current safely away from electrical equipment, they do not actively react to an impending lightning strike. Active shielding systems respond faster to a strike.
What is a lightning protection system (LPS)?His lightning protection system (LPS) has repeatedly proven its effectiveness and has been gradually refined during the past 2 centuries. For ordinary facilities, it assures reliable and affordable protection when designed and installed in accordance with NFPA 780: Standard for the Installation of Lightning Protection Systems.
Who should install a lightning protection system (LPS)?LPSs should be designed and installed by specialist firms employing individuals whose qualifications include Lightning Protection Institute certification. Owners of critical structures should also require third-party certification by the Lightning Protection Institute Inspection Program (LPI-IP) or UL Master Label program.
