In this month's issue of
our newsletter we continue our series "Removing Ambiguity Within
Power Quality Terminology" focusing this month on Power Sags/Undervoltage.
Sag is a reduction of
AC Voltage at a given frequency for the duration of 0.5 cycles to 1
minute's time.
Sags are usually caused
by system faults, and are also often the result of switching loads with
heavy start up current.
Unfortunately, different
terminology has been used to describe sags creating confusion and making
it difficult to discuss study and propose accurate solutions to resolve
these power quality problems.
Download our article
for a simple understanding of Sags
including causes and solutions.
Whether you're in need
of UPS Systems, Power Conditioners, Batteries, Switching Power Supplies,
Telecom DC Power Products, cooling systems, packaging solutions, or a
complete end-to-end power protection system, Power Solutions offers the
largest variety of products manufactured by the names you trust.
We appreciate your
business and your referrals.
Kind Regards,

Sags - Causes and Solutions
Sag is a reduction of AC
Voltage at a given frequency for the duration of 0.5 cycles to 1 minute's
time. Sags are usually caused by
system faults, and are also often the result of switching loads with
heavy start up current.
Sags account for the vast majority of power problems
experienced by end users. They can be generated both internally and
externally from an end users facility.
Common causes for sags include starting large loads, such as
a large Air Conditioning Unit. Similarly, the starting of large motors
inside an industrial facility can result in significant voltage sag. A motor can draw more than 6 times its
normal running current while starting.
Creating these large and sudden electrical loads will likely cause
a significant voltage drop.
