Abstract
The Seeker+ captures voltage sags with no setup, recording RMS values and waveforms for each event and sending them up to PQ Canvass. This paper gives a short overview of voltage sags, then walks through a real sag recorded by a Seeker+: finding it in PQ Canvass, reading its waveforms and RMS values, and using them to tell what caused the sag, which phases were hit, and which side of the recorder it came from.
