•
Default setting
(_:14011:148) VT supervision time delay
=
10 s
With the
VT supervision time delay
parameter, you set the time for which exceeding the voltage
supervision threshold does not lead to a blocking.
Parameter: Circul. current blocking
•
Default setting
(_:14011:149) Circul. current blocking
=
on
With the
Circul. current blocking
parameter, you switch the supervision of the circulating reactive
current off or on.
Parameter: Circul. current threshold
•
Default setting
(_:14011:150) Circul. current threshold
=
150 %
With the
Circul. current threshold
parameter, you set the level at which the supervision must be acti-
vated.
Parameter: Circul. current time delay
•
Default setting
(_:14011:151) Circul. current time delay
=
30 s
With the
Circul. current time delay
parameter, you set the time for which exceeding the threshold
value of the circulating reactive current supervision does not lead to a blocking.
