Qualitrack
QualiTrack is a portable single-phase power-quality logger, for surveys where harmonics, dips and swells are what matter.
1 · What it is
QualiTrack is a portable single-phase energy and quality-of-supply recorder. Alongside the usual energy figures it captures the power-quality detail, harmonics up to the 19th, voltage dips and swells, the things that wear equipment and trip sensitive loads. Like PowerTrack it's fitted for a study and the data downloads over USB for analysis. It suits quality-of-supply investigations, load studies and costing work on a single feed.
2 · What it records
Voltage live-to-neutral and neutral-to-ground; current to 100 A via a clamp CT; real, reactive and apparent power and power factor; and kilowatt-hours. On the power-quality side it records harmonics to the 19th and logs voltage dips and swells, and it keeps on-board statistics, highest and lowest voltage, highest current, peak kVA demand and energy used.

4 · Where it's used
QualiTrack is a standalone instrument. Like PowerTrack, it doesn’t report to the Augos platform: the data downloads over USB into its own installed software for analysis. It’s used for one-off power-quality surveys on a single feed, where harmonics, dips and swells are the question.
5 · Common questions
What does QualiTrack capture that a standard logger doesn’t?
Power-quality detail: harmonics up to the 19th, and voltage dips and swells. These are the disturbances that wear equipment and trip sensitive loads, and they don’t show up in energy figures alone.
When do I need a power-quality survey?
When sensitive equipment is tripping or failing early and the cause isn’t obvious. The dips, swells and harmonic detail QualiTrack records are often where the answer is.
Single phase or three phase?
QualiTrack is single-phase. For a three-phase load study, the portable PowerTrack is the right tool.
How does the data come off it?
Over USB, for analysis once the survey is done. It also keeps on-board statistics such as highest and lowest voltage and peak demand.
