WHAT IS A POWER EVENT?
Sags, surges, noise, spikes, blackouts…what really happens to connected devices when they experience a power anomaly? A lightning strike is a frequent example, although it is just one of countless problems that can strike your equipment. Imagine lightning has just struck a nearby transformer. If the surge was powerful enough, it travelled instantaneously through wiring (AC, network, serial, phone lines and more) with the electrical equivalent force of a tidal wave. For PC users, the surge could have traveled into your computer via the AC outlet or phone lines. The first casualty is usually a modem or motherboard. Chips go next, and data is lost. Lightning Facts The utility responds to overvoltages by disconnecting the grid. This creates brownouts and blackouts. If the voltage drops low enough, or blacks out, hard disks in computing machinery may crash, destroying the data stored on the disks. In all cases, work-in-progress stored in cache is instantly lost. In the worst case, password protection on the hard drives can be jumbled, or the file allocation tables may be upset, rendering the hard disks useless. Are you protected?
