Sag and Swell Detection
The PowerMonitor 5000 unit continually monitors line voltages and sets an
alarm flag when the voltage varies below (sag) or above (swell) a predetermined
threshold, expressed as a percentage of the nominal system voltage. The
PowerMonitor 5000 models detect and report sags and swells in different ways:
• The M5 model detects sags and swells and reports them in the Alarm Log.
• The M6 and M8 models retain the simple sag/swell capabilities of the
M5 model but also permit you to adjust sag and swell thresholds. In
addition, fixed sag and swell thresholds corresponding to definitions found
in IEEE 1159 and EN 50160 independently detect and report sags and
swells. When sags or swells are detected, these models record waveforms
and record detailed event information in the Power Quality Log.
