Frequently Asked Questions
What is power quality analysis?
Power quality analysis measures your electrical supply characteristics — voltage stability, harmonic distortion, power factor, and transient events — to identify conditions that damage equipment or waste energy.
How does poor power quality damage equipment?
Voltage sags, swells, harmonics, and transients stress motors, variable speed drives, and sensitive electronics, shortening their lifespan, increasing heat generation, and causing nuisance tripping and unplanned downtime.
How long does a power quality study take?
A typical study involves monitoring your electrical system over 7–14 days to capture all operating modes and load cycles. We then analyse the data and deliver a report with prioritised recommendations.
