1290 F2-C: Voltage deviation too
high
Capacitance monitoring not per-
formed in field 2 due to the volt-
age deviation in the 3 phases of
the reference system being too
high.
Check the reference system and
the wiring in field 2.
-
1291 F2-C: Measured voltage too
low
Capacitance monitoring not per-
formed in field 2 due to the volt-
age on the bushing coupling units
being too low.
Check the bushing coupling units,
the wiring, the bushings and the
transformer operating conditions
in field 2.
-
1292 F2-C: Limit value ΔC1 >
phase L1
The first limit value for the devia-
tion in capacitance has been ex-
ceeded for the bushing of phase
L1 in field 2.
Check capacitance changes in
field 2. If ∆C1 is greater than 5%,
disconnect the transformer from
the grid. Use an external measur-
ing device to measure capaci-
tance.

1293 F2-C: Limit value ΔC1 >
phase L2
The first limit value for the devia-
tion in capacitance has been ex-
ceeded for the bushing of phase
L2 in field 2.
Check capacitance changes in
field 2. If ∆C1 is greater than 5%,
disconnect the transformer from
the grid. Use an external measur-
ing device to measure capaci-
tance.
A
1294 F2-C: Limit value ΔC1 >
phase L3
The first limit value for the devia-
tion in capacitance has been ex-
ceeded for the bushing of phase
L3 in field 2.
Check capacitance changes in
field 2. If ∆C1 is greater than 5%,
disconnect the transformer from
the grid. Use an external measur-
ing device to measure capaci-
tance.
A
1295 F2-C: Limit value ΔC1 > multi-
ple phases
The first limit value for the devia-
tion in capacitance has been ex-
ceeded for the bushings of multi-
ple phases in field 2.
Check reference system and ca-
pacitance changes in field 2. If
∆C1 is greater than 5%, discon-
nect the transformer from the grid.
Use an external measuring de-
vice to measure capacitance.
A
1296 F2-C: Limit value ΔC1 >>
phase L1
The second limit value for the de-
viation in capacitance has been
exceeded for the bushing of
phase L1 in field 2.
Check capacitance changes in
field 2. If ∆C1 is greater than
10%, there is a risk of explosion.
Disconnect transformer from the
grid immediately. Use an external
measuring device to measure ca-
pacitance.
A
1297 F2-C: Limit value ΔC1 >>
phase L2
The second limit value for the de-
viation in capacitance has been
exceeded for the bushing of
phase L2 in field 2.
Check capacitance changes in
field 2. If ∆C1 is greater than
10%, there is a risk of explosion.
Disconnect transformer from the
grid immediately. Use an external
measuring device to measure ca-
pacitance.
