Power Quality · 7 min read · Published 2026-07-17 · Updated 2026-07-17
A power quality audit identifies whether production problems are caused by voltage fluctuation, harmonics, poor power factor, imbalance, wiring issues or load behavior.
Before measurement
List critical machines and symptoms
Collect electricity bills and penalty details
Note production shift timings
Identify recent equipment failures
Mark transformer and panel ratings
Measurements to capture
Voltage and current trend
Phase imbalance
Power factor and kvar demand
THD voltage and THD current
Load peaks and dips
Neutral current and temperature observations
After the audit
The audit findings should lead to a practical recommendation: stabilizer, APFC, SVG, harmonic filter, UPS, transformer correction, cable improvement or a combination.
