Basic harmonics study
THD measurement (V & I)
Discover the source of distortion in your installation, so
that you can filter those loads or move them to separate
circuits.

Utility PQ benchmarking
Phase sequence components
Before you install sensitive loads, make sure you
understand the existing quality of power delivered by
your utility. Comparing benchmarks over time can help
pinpoint potential areas of concern.
