8. head of projected life span Causes Outside Your Facility Lightning natural disasters and inclement weather can cause high transient power line voltages that can adversely affect your power supply Utility switching and faults on the utility s distribution system can adversely affect the quality of your power before it even reaches your facility Why Many utility systems are aging and few power plants have been built over the last decade With increased demand for power their supply margins are dipping dangerously low The farther away from the source of power the greater the risk of power quality problems Causes Inside Your Facility According to some studies 3 4 of all power disturbances are caused by equipment inside your building If your facility is more then a decade old chances are the wiring was not designed to support the intensive use of electronic equipment In industrial facilities these problems are even more complex In fact any device that runs in cycles can create a drain or a surge when it switches on or off The more power the equipment uses the bigger the affect Even something as small as a copier or a laser printer can cause problems in sensitive equipment that share the same line The Complete Protection Experts Of course you can t control how power is distributed But you can protect the equipment in your facility from power surges and transients by installing equipment such as surge sup
