Description
df/dtdf/dt
df/dt monitoring is carried out
according to the parameters
described in
Ph-shift,df/dt
Phase shift monitoring and df/dt
monitoring is carried out. Tripping
occurs if phase shift or df/dt is
triggered.

Monitoring
2
[1- and 3-phase]
During single-phase voltage
phase/vector shift monitoring,
tripping occurs if the phase/vector
shift exceeds the configured
threshold value (parameter
) in at least one of the three
phases.
3-phase
During three-phase voltage phase/
vector shift monitoring, tripping
occurs only if the phase/vector
shift exceeds the specified
threshold value (parameter
) in all three phases within
2 cycles.
Notes
If a phase/vector shift occurs in
one or two phases, the single-
phase threshold value
(parameter
) is taken
into consideration; if a phase/
vector shift occurs in all three
phases, the three-phase threshold
value (parameter
) is
taken into consideration. Single
phase monitoring is very sensitive
and may lead to nuisance tripping
if the selected phase angle
settings are too small.
3 phase mains phase shift
monitoring is only enabled if
Mains voltage measuring
(parameter
configured to "3Ph 4W" or "3Ph
3W".

If the electrical angle of the mains
voltage shifts more than this
configured value in any single
phase, an alarm with the class
configured in parameter
is initiated.

If the electrical angle of the mains
voltage shifts more than this
configured value in all three
phases, an alarm with the class
configured in parameter
is initiated.
