COLUMN - DEFINITIONS
Status/Partial: Contains two status indicators. The upper indicator refers to
the entire observation window’s PASS/FAIL result (same status as presented
in the Summary page), while the lower indicator is a PASS/FAIL indicator of
the most recent period. This recent indicator serves as real-time indicator &
typically reflects to only minutes to a few hours of history (this is dependent
on the specific PQ parameter measurement' intervals & method).
Observation: Indicates whether the observation of a s pecific PQ parameter
is complete.
Window/Interval: Upper Area - Provides t he observation window t ime
(contains h istorical d ata u sed f or t he ca lculations). You may un iquely s et
the observation period in User Defined Pages (Options - 1 or 2 H ours, or 1
Day, or 1 W eek, or 1 Y ear). Lower Area – Provides t he measurement
interval t ime or p arameter r esolution t hat f alls w ithin t he o bservation
window (the measured time length for the PQ parameter). The interval may
also be set in User Defined Pages (Options - 1, 3, 10 o r 20 s econds, or 1, 3,
10 or 30 m inutes, or 1 , or 2 H ours, or 1 Day). I f y ou c onfigure y our P Q
Compliance t o a s et standard ( i.e. EN50160), t he O bservation Window &
Interval Time will be calculated according to the standard.
Time OK/Time FAIL: provides t he p ercentage o f t ime t he P Q p arameter
was O K ( as g reen t ext o n t he u pper ar ea) & p ercentage o f t ime t he P Q
parameter was outside the defined limits or FAILED (as red text in the lower
area) for the entire observation period (Observation Window). Example as
per the Information Window: if Voltage Dips was observed for a period of 1
week at a r esolution o f 1 0 m s ( interval), t he P Q p arameter was O K f or
97.647% & FAILED for 2.352% of the time (observation week). I t should not
be confused to the lower area on the previous column.
Time N/A: Provides the percentage of time the unit was not measuring due
to lack of power.
Total Events: Provides the overall number of P Q e vents i nfluenced by the
PQ parameter in the observation window.
