14 Limit value P<< Value has fallen below the limit
value for active power P<<.
Check the current operating con-
ditions of the transformer and the
set P<< parameters.
-
15 Limit value P> The limit value for active power
P> has been exceeded.
Check the current operating con-
ditions of the transformer and the
set P> parameters.
-
16 Limit value P>> The limit value for active power
P>> has been exceeded.
Check the current operating con-
ditions of the transformer and the
set P>> parameters.
-
17 Limit value Q< Value has fallen below the limit
value for reactive power Q<.
Check the current operating con-
ditions of the transformer and the
set Q< parameters.
-
18 Limit value Q<< Value has fallen below the limit
value for reactive power Q<<.
Check the current operating con-
ditions of the transformer and the
set Q<< parameters.
-
19 Limit value Q> The limit value for reactive power
Q> has been exceeded.
Check the current operating con-
ditions of the transformer and the
set Q> parameters.
-
20 Limit value Q>> The limit value for reactive power
Q>> has been exceeded.
Check the current operating con-
ditions of the transformer and the
set Q>> parameters.
-
21 Limit value cos φ< Value has fallen below the limit
value for power factor cos φ<.

ditions of the transformer and the
set cos φ<< parameters.
-
23 Limit value Pos< Value has reached or fallen below
the limit value for tap position
Pos<.
Check the current operating con-
ditions of the transformer and the
set Pos< parameters.
-
24 Limit value Pos> Value has reached or exceeded
the limit value for tap position
Pos>.

-
25 Function monitoring The control variable is outside of
the bandwidth.
Check the current operating con-
ditions of the transformer and the
set bandwidth.
-
26 Switching direction control The target tap position has not
been reached.
Check the connections for the
raise and lower contacts and the
functionality of the tap-changer
activation.
-
27 Lower bandwidth limit value Value has fallen below the lower
bandwidth limit value.
The bandwidth is set too low.
Check the parameter.
-
28 Upper bandwidth limit value Value has exceeded the upper
bandwidth limit value.
The bandwidth is set too high.
Check the parameter.
-
29 Switching interval monitoring:
Total tap-change op.
The maximum number of total
tap-change operations has been
exceeded.
Check the set number of total tap-
change operations and the cur-
rent operating conditions of the
affected network segment.
