Power Quality Services
EWEB is committed to providing reliable power to you. We design, maintain, and operate
our system with reliability as a primary goal. Unfortunately, reliable power is
not perfect power. System events, including events on transmission lines hundreds
of miles away, cause disturbances in the power we supply you. While these events
are not frequent, they can cause problems for your sensitive equipment if you are
Utility systems are usually a minor source of power quality problems. Studies show
that 65 to 85 percent of power quality problems originate in customers homes or
businesses. Problems with grounding, neutrals, wiring, harmonics generated by equipment,
and other sources can interfere with or damage other equipment in your facility.
There are many techniques and products available to help minimize the impact of
power quality problems in your home and business.
For more information about power quality, see the Surge Sheet, Sags, Spikes and Surges and Harmonic Distortion: Problems and Solutions.
EWEB has voltage recorders at various substations across our electrical system.
If you saw the lights blink momentarily or had some equipment power off for no apparent
reason, perhaps it was due to a system wide transmission outage. To view the most
recent power system disturbance recorded, see
