Description

Some meters make the distinction between a voltage "sag" and an "undervoltage", a "swell" and an "overvoltage." We don't have the way in the std to make that distinction (except to perhaps also supply a voltage captured with the alarm.) However, users like to set different thresholds for these events and let the presence of the event indicate that the threshold was exceeded. It would be useful to provide separate events for each severity.

Proposed Solution

Add new enumeration codes to E.8 to say "High", "HighCleared", "Low", and "LowCleared".
This might be used with a sequence that says "electricMeter.power.phaseAVoltage.High"
Alternatively, we might say "Over", "OverCleared", "Under" and "UnderCleared" but this seems more awkward.
