When is the last time your facility was subjected to an electrical power surge? Chances are, you have no idea – for two very good reasons. First, power surges are typically very brief – lasting only a few milliseconds. Secondly, most power surges are relatively small and go unnoticed, unless they are significant enough to make the lights flicker. Even so, they remain dangerous to your systems and should not be ignored – they are a silent killer of your critical electronic equipment.
