WHERE DO POWER QUALITY ISSUES ORIGINATE?

Poor power quality is characterized by electrical disturbances, such as transients, surges, sags, power interruptions and harmonics. The disturbances can originate externally without warning, but are often generated within your facility.

Eighty percent of electrical disturbances that cause poor power quality come from within your facility. Powering on and off very large equipment, wiring errors, poorly specified or improperly serviced power conversion equipment, grounding loops and even normal daily operations can foster power quality issues that lead to production disturbances and lost data.

Severe weather, utility fault clearing, power line accidents and other external network issues like grid switching or power-factor correction capacitors represent the remaining twenty percent of power quality problems. These disturbances often generate spikes or power interruptions that can instantly damage equipment. Worst of all, these incidents are completely unpredictable and beyond anyone’s control.
