In
, one phase is in dip and two phases have a swell indication. For the
Phase
Mode Dip
value "Three Phase", the activation occurs only when all the phases are active.
Furthermore, both swell and dip variation event detections take place simultaneously. In
case of a concurrent voltage dip and voltage swell, both SWELLCNT and DIPCNT are
incremented by one.
Phase Mode
value "Three Phase", two different time
moment variation event swell detections take place and, consequently, DIPCNT is
incremented by one but SWELLCNT is totally incremented by two. Both in
it is assumed that variation durations are sufficient for detections to take
place.
