The scenario
Continuous electrical parameter monitoring detects voltage sag and swell events by comparing measured RMS voltage against nominal thresholds, triggering alarms and logging events.
What is in this drawing
Read the decisions behind it.
01
Check if voltage is below 90% nominal to trigger sag alarm
02
Check if voltage is above 110% nominal to trigger swell alarm
03
Log normal readings and continue sampling loop
Use for power quality monitors, UPS systems, industrial automation panels, or any equipment requiring voltage anomaly detection and alerting.
