2 T RANSIENT V OLTAGE S URGES: A GROWING P ROBLEM POWER DISTURBANCES Lightning and fluctuations in utility power (caused by grid switching, for example) are often assumed to be the main sources of power disturbances. However, the overwhelming cause is actually equipment, such as motors and appliances, turning on and off. Even simply switching lights on and off will cause electrical surges. In fact, it is estimated that 65% of all transient voltage surges are generated from inside sources, while only 35% come from outside. KEY CAUSES OF TRANSIENTS: Lightning Variable Frequency Drives Utility Accidents AC Chillers Utility Switching Pumps Motors LOCATION VARIABLES THAT INCREASE THE RISK OF EXTERNAL TRANSIENTS High lightning activity At the end of a utility line On a transmission line downstream of industrial facilities At a higher elevation than surrounding structures In an open rural location Utility industry experts estimate that problems resulting from transient voltage surges cost U.S. companies a stunning $26 billion annually. This figure not only includes the high price of direct damage to electrical distribution systems, electronic equipment and microprocessor controllers, but also the crippling cost of lost productivity. Facility downtime, lost data, lost orders and the disruption of critical processes can seriously reduce productivity. This means that minimizing the risk of damage from electrical surges is an absolute priority for companies of all types, all across the globe.
