1.3 What is a voltage swell?
A voltage swell is the opposite of a voltage sag. It is a brief increase
in RMS voltage on the
AC power circuit. Although the negative impacts
of small voltage swells are rare, certain types of equipment are highly
susceptible to these fluctuations. As a result, some international
standards also address these types of events.
1.4 Why generate sags and swells?
The simplest way to solve voltage sag and swell problems is to
make your equipment immune to common voltage sag/swell events.
And the simplest way to increase sag/swell immunity is to apply sags
and swells of controlled depth and duration to the equipment, find out
what goes wrong, and fix it.
Your IPC lets you provide poor quality power to your equipment
under test. It can apply sags/swells of controlled depth and duration to
your equipment, and records how your equipment responds.
1.5 Why use a multi-channel data acquisition system?
It isn’t necessary to use a multi-channel data acquisition system
during sag testing, but it helps.
If you simply need to verify that your sensitive equipment can
tolerate a particular range of voltage sags, a data acquisition system is
not necessary. Just apply the sags, and see if your equipment works.
However, if your equipment does misbehave, it is useful to know
exactly what happened.
Your IPC contains many channels of high-
speed data acquisition. Some of these channels are permanently
connected to ac power voltages and currents, but many of them are
available for you to use any way you like.
You can use these uncommitted channels to monitor high voltages
and low voltages inside your equipment. Common monitoring points
include power supply outputs, emergency shutdown contacts, reset
lines, and unbalance detection lines.
With the data gathered by your IPC data acquisition system, you
will quickly determine how and why your equipment is misbehaving.
A solution is often easy to design and install, and you can re-test to
verify that you have, in fact, increased your voltage sag immunity
.
1.6 Useful technical features of your IPC
Your IPC sag swell generator is unique in that it has been designed
to address a wide variety of testing applications, ranging from a quick
test of a small power supply or relay, to a detailed study of a
sophisticated and complex manufacturing tool.
A patent-pending transformer design enables your IPC to generate
voltage sags, swells, and interruptions, ranging from 0% to 125% of
the nominal voltage.
A patent-pending power switching technology combines the best
features of IGBT
switches and electromechanical relays. This design
allows for both gapless switching and long duration events.
