These are just some of the symptoms of power quality problems found in wiring systems that were designed for the needs of yesterday. Yes, these symptoms met, and probably still meet, electrical codes. But the codes are not intended to provide for a system free of transients, power surges, voltage sags and spikes, and other interruptions that can cause expensive downtime or erratic data operations. A recent study indicates that the average office building experiences 106 such power quality problems in a typical month. Most of these disturbances originate right within the building.
Computers generate the very harmonics they're sensitive to.
Personal computers, laser printers and other switched-mode power supply equipment within your building are usually the culprits for most of the power supply irregularities affecting other computers. It's a problem that has only recently begun to be recognized in the building industry, as more and more computers and similar equipment are installed, turning the modern office or factory into a high-tech computer environment. In new construction or renovation, many power disturbances can be prevented or significantly lessened by designing for power quality assurance, at surprisingly small cost. Savvy tenants know what to look for when shopping for space. They want a facility that meets their power needs now, and in the future.
