Home/Power Quality Audit/Voltage Fluctuation Study

Voltage Fluctuation Study

Sag and swell event capture and classification, correlated against process trips and equipment nuisance faults.

Scope of work

  • Continuous Class A monitoring for sag/swell/interruption events per IEC 61000-4-30
  • Event classification by magnitude, duration and phase involvement (ITIC/CBEMA-style)
  • Correlation of recorded events against logged process trips or equipment faults
  • Source identification — utility-side vs. facility-internal switching events

Deliverables

  • Event log with magnitude/duration classification
  • Correlation report linking events to production or equipment impact
  • Ride-through / mitigation recommendation — UPS, DVR, or process-side hardening
