What is the difference between lightning protection and surge protection?
This is a topic that can get quite lengthy in discussion. Think of lightning protection as a means to protect equipment, facilities and people from the effects of nearby or direct lightning events. Whereas, surge protection provides protection to equipment from the effects of more distant lightning events and/or power system anomalies. In purely scientific terms, lightning can be described by a waveform of 10/350µs, while surges are described by an 8/20µs. Many domestic companies only design products capable of handling surge waveforms, while some European companies, DEHN included, design products capable of handling lightning waveforms.
