I downloaded the CSV data and noticed that a dip threshold appears to be <110v, not the -10% (108v) suggested in the text. At 110v threshold I have 74 hits, at 108v I have 13 hits.
Where should this threshold really be to ignore the dips from starting motor loads?
I have a ground source heat pump that seems to be the major culprit. I have had it tested recently and it is performing within spec.
