... Surge Line Protection Modules General Description Surge is defined as a high-energy, short-duration pulse caused by lightning or the switching of power loads. In short, a surge can be a transient wave of voltage, current or power. Most of the surge pulse waveforms are unidirectional impulses. Surge wave- forms occur in many situations, including computer memory dri- vers and telecommunication equipment ...
