摘要

Almost every aspect of our daily lives, from filling up the car to shopping at the local supermarket, is permeated by electronic systems, and as such we, as a society, are increasingly reliant on these systems being run efficiently and continuously. The huge rise in the use of computers, electronic process controls and telecommunications over the last 20 years is there for all to see, however, not only are there more systems in existence, but the physical size of the electronics involved has reduced considerably. This reduction in size means less energy is required to damage components. Lightning activity during thunder storms or electrical switching events can cause very short duration increases in voltage on mains power and/or data communication/signal/telephone lines, with potentially devastating consequences. These increases in voltages are called surges or transient over voltages. A lightning surge is severe enough to present a risk of loss of life through fire and/or electric shock hazards through a dangerous f lashover. This can occur when the surge voltage exceeds the withstand rating of the cable insulation or equipment.
