Lightning and Over Voltage Protection

DESCRIPTION

Physical lightning protection, a high-integrity single point grounding system and appropriate surge protection are the most effective means of assuring minimum risk exposure to transient over voltage events whether caused by load switching, lightning, or other EMP sources. This one day course discusses these threats and the industry best practices to defend against them.
