30 Switching interval monitoring:
Lower tap-change op.
The maximum number of lower
tap-change operations has been
exceeded.
Check the set number of lower
tap-change operations and the
current operating conditions of
the affected grid segment.
-
31 Switching interval monitoring:
Raise tap-change op.
The maximum number of raise
tap-change operations has been
exceeded.
Check the set number of raise
tap-change operations and the
current operating conditions of
the affected grid segment.
-
32 Reversal of power flow A reversal of power flow is
present.
Check the current operating sta-
tus of the transformer and the po-
larity of the current transformer if
necessary.
-
33 R&X compensation calcula-
tion
R&X compensation cannot be
calculated.
The set parameters do not allow
a calculation of R&X compensa-
tion. Check the set parameters.
-
34 Z compensation calculation Z compensation cannot be calcu-
lated.
The set parameters do not allow
a calculation of Z compensation.
Check the set parameters.
-
35 No master present No master is present in the paral-
lel operation group.
Specify a TAPCON® as the mas-
ter for parallel operation and
check whether the master is
ready for operation.
-
36 Masters on CAN bus > 1 Several masters are present in
the parallel operation group.
Ensure that just one TAPCON® is
specified as the master in the par-
allel operation group.
-
37 Permitted tap difference The permitted tap difference has
been exceeded.
Check the current operating con-
ditions of the transformers in par-
allel operation as well as the set
parallel operation parameters of
the TAPCON® units involved.
-
38 Tap difference to follower A tap difference to a follower ex-
ists.
Check the current operating con-
ditions of the transformers in par-
allel operation as well as the set
parallel operation parameters of
the TAPCON® units involved.
-
39 Tap difference to master A tap difference to the master ex-
ists.
Check the current operating con-
ditions of the transformers in par-
allel operation as well as the set
parallel operation parameters of
the TAPCON® units involved.
-
40 Different parallel operation
methods
Different parallel operation meth-
ods have been set for multiple
TAPCON® units.
Check the set parameters. Set
the same parallel operation
method for each TAPCON® in
the parallel operation group.
-
41 Circulating reactive current
blocking limit
The permitted circulating reactive
current blocking limit has been
exceeded.
Check the current operating con-
ditions of the transformers in par-
allel operation as well as the set
circulating reactive current block-
ing limit of the TAPCON® units
involved.
