Content introduction

This section identifies transient source and damage, waveforms and amplitudes of projected transients on different types of lines, frequency of transient occurrence, and effective methods to implement to preclude equipment damage and operational upset when transients occur. (a) Electrical and electronic equipment comprising an operating system is susceptible to damage from lightning-generated transient surges via two primary sources - transient surges coupled to equipment from incoming commercial ac power conductors and transient surges coupled to equipment by connected facility control, status, power, ground, and data and signal lines that originate or terminate at equipment located externally to the building or structure housing the equipment of interest. (b) Damage resulting from lightning-generated transients occurs in many forms. Entire equipment chassis have been exploded and burned, and wall-mounted equipment has been blown off the wall by large-magnitude transient energy. Damage usually consists of catastrophic component failure or shortened operating lifetime of components resulting from over-stress.
