Configure Power Quality; Power Quality Settings - Arbiter Systems 928A User Manual

Configure Power Quality
Use this section to assist you in configuring the 928A
to detect sags and swells by using Point Limits similar
to a CBEMA method. Make sure to review the section
entitled "Power Quality – Sags and Swells" on page 48.
Figure 4 illustrates how progressive limits over speci-
fied time intervals can be applied to detecting sags and
swells.
There are two separate setup screens in Mlink for
configuring Power Quality triggering in the 928A: the
first screen is tabbed "Settings" and the second is
tabbed "Point Limits". These are depicted in Fig-
ures 12 and 13.
The Settings screen sets up some basic things about
the measured signal and how the point limits are com-
pared to it. Check through the values listed in the
screen shot illustrated in Figure 12 and compare them
with the definitions on the following pages.
