The following transformer values are used to determine the minimum band-
width:
Nominal voltage U
N
= 11000 V
Step voltage in tap position 4 U
Step4
= 11275 V
Step voltage in tap position 5 U
Step5
= 11000 V
Delay time T1
Delay time T1 delays the issuing of a tap-change command for a defined pe-
riod. This prevents unnecessary tap-change operations if the tolerance
bandwidth is exited briefly.
Response to delay time T1
If the control variable
is within the set bandwidth
, no control com-
mands are issued to the motor drive unit for the tap change. Control com-
mands will also not be issued to the motor-drive unit if the control variable
returns to the bandwidth
within the set delay time T1
. However, if the
control variable deviates from the set bandwidth for a long period
, a tap-
