Power Quality

Every voltage sag, swell, transient, and interruption recorded by the island's power-quality meter, published as it happens. These are real instrument readings, not estimates and not outage reports. A brief sag is logged here as a sag, never as an outage.

How this log works

A Powerside PQube 3 power-quality meter (serial P3001520) installed at Treasure Island Wines monitors the island's 208 V three-phase service around the clock. When voltage moves outside its configured thresholds, the meter emails an event report with oscilloscope waveforms, and this page publishes it automatically.

Event categories are kept separate on purpose. A voltage sag is a dip that the lights ride through; an interruption means voltage fell to near zero. Conflating the two would inflate outage counts, so this log never does.

The meter is operated by Treasure Island Wines, which forwarded its event alerts to this project for publication as a public power-quality record. If you felt a flicker or lost power, report the outage so it can be matched against the instrument record.
