George, I discuss problems with powerline-spikes in chapter 8, Designing Power Supplies, of my bookElectronic System Design: Interference and Noise Control Techniques (Prentice-Hall, 1987, now out of print). For equipment that will be used indoors, you should try to design your equipment to

Hi George: Take a look at IEEE standard C62.41 ('Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits'). It has summaries of transient voltage surveys done by other people around the world. Other portions of the standard suggest specific types of surge tests test levels.

Hi Folks, I am trying right now to convince some folks that power line voltage spike problems can be and usually are severe enough to degrade or kill ITE products that don't have adequate over-voltage protection. I found a link using Google that describes the problems [
