Power quality surveys & load monitoring

Voltage, current, harmonic and power-factor monitoring for sensitive or high-demand sites, ahead of EV charger installs, new plant, or to diagnose nuisance tripping.

When you need a power quality survey

  • Nuisance tripping, flickering lights or unexplained equipment failures
  • Before adding EV chargers, heat pumps or new machinery, to confirm maximum demand
  • Harmonic distortion from variable-speed drives, LED lighting or IT loads
  • Poor power factor increasing energy bills

How it works

A class-rated analyser is installed at the main intake or a distribution board for typically 7 days, logging voltage, current, harmonics, flicker and events. You get a report with findings measured against relevant standards and practical recommendations, from load balancing to correction equipment.

FAQ

Power quality: frequently asked questions

How long does a power quality survey take?

Most surveys log for around seven days to capture a full working week, followed by analysis and a written report.

Do I need a load survey before installing EV chargers?

Often, yes. Confirming maximum demand shows whether the existing supply can take the extra load or whether load management or a supply upgrade is needed.
