EVENT STATUS SECTION
The Ev ents S tatus T able s hows a hi gh l evel P ASS o r F AIL i ndication o f e ach P Q
parameter. Any P Q p arameter that h as an in complete o bservation p eriod w ill b e
presented as N /A ( Not A vailable). T he d efinitions d efined b elow ar e PQ
Parameters Configured as per EN50160 compliance. You may choose any other PQ
Compliance or set your own Unique PQ Compliance:
Voltage Frequency OK/FAIL: Frequency c ompliance is b ased o n s tatistics:
N, N 1 & N 2. F requency m easurement in terval is 1 0 sec. in an en tire
observation wi ndow of 1 we ek. N - amount o f intervals. N 1 - intervals
frequency exceeded [+1.00%,-1.00%] from Nominal Frequency. N2 - intervals
frequency exceeded [ +4.00%,-6.00%] fr om N ominal F requency. N 1 & N 2
increment only if valid voltage inside nominal boundary of [+15.0%,-15.0%].
Compliance i f b oth N1/N < = 5% of t ime & N2=0 of t ime. I ntervals w ith
voltage i nterruption a re d iscarded. Intervals with DIPS or O ver v oltage a re
discarded.
Supply Voltage Variations OK/FAIL: Variations ar e evaluated by co llecting
statistics: N , N 1 & N2. S tatistics ar e c ollected as av erage v oltage w ithin
intervals o f 1 0 m in. in o bservation w indow o f 1 w eek. N - amount of
intervals. N 1 - intervals v oltage exceeded [ +10.0%,-10.0%] bou ndary of
nominal. N 2 - intervals v oltage exceeded [ +15.0%,-15.0%] boundary o f
nominal. Compliance i f N1/N <=5% & N2=0 during the entire o bservation
window. I ntervals w ith v oltage i nterruption ar e d iscarded. I ntervals w ith
DIPS or OVER Voltage are discarded.
Rapid Voltage Changes OK/FAIL: Rapid voltage change is based on a 3 sec.
window i n w hich R MS v oltage m inimum & m aximum v alues ar e o btained
(minimum/maximum v alues s hould b e w ithin + -10.0% fr om n ominal). T he
rapid change is the percent of delta between minimum & maximum divided
by av erage R MS o f 9 s ec. T he R apid p ercent r esults ar e ev aluated d uring
observation window of 1 week. Rapid changes are limited to specific count
(N): Rapids of more 5.00% allowed: N <= 65536 occurrences.
Supply Voltage Dips OK/FAIL: DIP is a voltage drop of more than 10.0% from
Nominal (but no more than 100.0%, & deactivate on 8.0%) DIP minimum time
is 10 ms. & maximum time of 1 min. DIP events are counted per all phases
combined within observation window of 1 week. Total events (N) allowed is:
20.
Short Interruptions OK/FAIL: Short in terruption is a v oltage d rop o f le ss
than 97.0% from nominal (event deactivate on 77.6%). Min duration 10 ms.,
Max duration 3 min. events are counted in the entire observation window of
1 week. Total events (N) allowed is: 2.
Long Interruptions OK/FAIL: Long interruptions are the same as short ones
but with a longer duration (longer than short interruption maximum time).
