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<. Check the current operating con-
ditions of the transformer and the
set cos φ< parameters. -
22 Limit value cos φ<< Value has fallen below the limit
value for power factor cos φ<<. Check the current operating con-
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>. Check the current operating con-
ditions of the transformer and the
set Pos> parameters. -
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. -
