4.Unbalance calculation
(Difference between maximum deviation from the mean value and mean value)/mean value *100%,if the mean
value of denominator is less than the rated value, the denominator is rated value; voltage rated value Ue; 3 phase 4
wire Ue as the phase voltage, menu setting 400V instrument as 220V*PT, 100V instrument as 57V*PT.Current
rated value Ie: 5A instrument as 5A*CT, 1A instrument as 1A*CT.
Unbalance set parameter in percentage, e.g. 20 means 20%.
