Voltage Sag and Swell Detection with Alarm Flowchart
Drawing preview
התרחיש

Continuous electrical parameter monitoring detects voltage sag and swell events by comparing measured RMS voltage against nominal thresholds, triggering alarms and logging events.

מה מופיע בתרשים הזה

פענחו את ההחלטות שמאחוריו.

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.
