Power Quality
PQ events, harmonics, power factor
Monitor power quality against IEEE 519 harmonic distortion limits and IEC 61000 electromagnetic compatibility standards. Detect voltage events, track total harmonic distortion, and manage power factor to avoid utility penalties — protecting both your equipment and your bottom line.
PQ event detection
Automatic detection and classification of voltage sags, swells, and transients per IEC 61000-4-30 measurement standards. Analyze events against the ITI (CBEMA) curve to determine whether voltage deviations fall within equipment tolerance envelopes.
Harmonic analysis
Monitor total harmonic distortion (THD) and individual harmonics up to the 50th order against IEEE 519 recommended limits. Track THD trends at the point of common coupling and identify harmonic sources from VFDs, UPS systems, and nonlinear loads.
Power factor tracking
Track power factor trends across your facilities and receive alerts before crossing utility penalty thresholds — typically 0.90 lagging in GCC utility tariffs. Model the financial impact of capacitor bank investments against penalty avoidance savings.
Equipment protection
Correlate PQ events with equipment trip logs and maintenance records to identify failure patterns. Quantify the cost of PQ-related downtime and prioritize mitigation investments — from surge protection to active harmonic filters.
How it connects
Power quality data enriches Dashboard facility scorecards with equipment health indicators. THD and power factor trends feed into Optimization for capacitor bank sizing and load balancing decisions.
