Reaction
You can use this parameter to set the behavior of the device if the measured
value is higher than the upper limit (> or >>) or lower than the lower limit (<
or <<). You can select the following options:
Setting
Behavior
Off
No reaction.
High-speed return
For U</U<<: The device performs tap-change opera-
tions in the raise voltage direction (U+) until the mea-
sured voltage is back above the limit value.
For U>/U>>: The device performs tap-change opera-
tions in the lower voltage direction (U-) until the mea-
sured voltage is back below the limit value.
With high-speed return, the device ignores the set delay
time of automatic voltage regulation.
Auto blocking
Automatic regulation is blocked.
You can continue to perform tap-change operations in
manual mode.
Auto/manual blocking
Automatic regulation is blocked.
You
cannot
perform tap-change operations in manual
mode.
Table 36: Behavior when an event message is issued
Hysteresis
You can use this parameter to set the hysteresis. You can use this to avoid
the unnecessary generation of messages if the measured value fluctuates
around a threshold value.
Delay time
You can use this parameter to set the delay time in order to delay the issuing
of the event message.
9.2.3 Current monitoring
For monitoring the transformer's current load current, you can set 4 limit val-
ues:
▪ I<<: Lower limit 2
▪ I<: Lower limit 1
▪ I>: Upper limit 1
▪ I>>: Upper limit 2
