Additionally, in the FG mode, each kind of fault has its own particular parameters to be modified
by the user. These parameters are listed below:
Parameters of
Voltage Dip
*
Allowed range of values
Voltage of fundamental harmonics of phases U,
V, W
0-100%
0% means 0V
Angle of fundamental harmonics of phases U, V,
W
0-360°
*The harmonic content during the voltage dip is the same as the content before the voltage dip
but there is no harmonic control while the voltage dip is taking place, so harmonic phase delay
may change.
Example Voltage Dip: U%=100, V%=50, W%=50; Uº=0, Vº=60, Wº=300
Parameters of
Over/Under Voltage
Allowed range of values
Voltage of fundamental harmonics of phases
U,V,W
0-120%
0% means 0V
