260 Limit value ∆U-3ph The limit value for the difference
in voltage between the three
phases has been exceeded.
Check the current operating con-
ditions of the transformer and the
set parameter ∆U-3ph.
-
263 Limit value ∆φ-3ph The limit value for the angle dif-
ference between the three
phases is exceeded.
Check the current operating con-
ditions of the transformer and the
set parameter ∆φ-3ph.
-
266 Test tap or configuration faulty The connection and/or configura-
tion of the three-phase measure-
ment is faulty.
Inspect the connection of the cur-
rent transformer and voltage
transformer and the configuration
of the three-phase measurement.
-
267 cosφ interpolation active The parallel operation is carried
out with interpolated values.
No CAN bus communication with
other TAPCON® units present.
Check wiring as per connection
diagram.
-
272 Limit value ∆φ< Value has fallen below the limit
value for phase angle difference
∆φ<.
Check the current operating con-
ditions of the transformer and the
set ∆φ< parameters.
-
273 Limit value ∆φ<< Value has fallen below the limit
value for phase angle difference
∆φ<<.
Check the current operating con-
ditions of the transformer and the
set ∆φ<< parameters.
-
274 Limit value ∆φ> Value has exceeded the limit
value for phase angle difference
∆φ>.
Check the current operating con-
ditions of the transformer and the
set ∆φ> parameters.
-
275 Limit value ∆φ>> Value has exceeded the limit
value for phase angle difference
∆φ>>.
Check the current operating con-
ditions of the transformer and the
set ∆φ>> parameters.
