Special Parameters Aggregation

Parameter	Special Method of Aggregation
Voltage Under Deviation	where n = the number of 10/12-cycle r.m.s. values for underdeviation during the aggregation interval and Urms−under,i is the ith 10/12-cycle r.m.s. value
Voltage Over Deviation	where n = the number of 10/12-cycle r.m.s. values for overdeviation during the aggregation interval and Urms−over,i is the ith 10/12-cycle r.m.s. value
Flicker	10-min Interval: Aggregated on the basis of the probability distribution function for the instantaneous flicker values 2- hour Interval: Aggregated on the basis of the last 12 values of short term flicker values according to the following method
Instantaneous Flicker	Aggregated by taking the average of the measured values in 10 min
Power (Instantaneous)	Aggregated by taking the Average of the measured values in the aggregation intervals (150/180 Cycles, 10-min)
Power Demand (Quantity and Value)	Aggregated by taking the Average of the measured values in the demand interval which is input by the user.
Energy	Aggregated by taking the Average of the measured values in 10 min (reset each 10 min) (no accumulation)
Accumulated Energy	Aggregated by accumulating each 1 min without reset
