Bug fixing:
●
The fault data for differential current and
restraining current issued by the ground
differential protection functions REF_2 and REF_3
are now also calculated correctly when the
operating mode is set to “Low imped. / IP,max”
(previously they had twice the value).
REF_x When the differential protection is triggered these
functions are now blocked as long as at least one of the
following conditions is met:
●
DIFF: Meas.system 1 trigg. (041 124)
●
DIFF: Meas.system 2 trigg. (041 125)
●
DIFF: Meas.system 3 trigg. (041 126)
CBF_x Timer stages ‘t1 3p’ and ‘t2’ of functions CBF_2…CBF_4
are now processed regardless of the setting at CBF_1.
IEC The ICD files have been modified. urcbMX has been
added to the logical nodes PhsPDIF1, Rf1PDIF1,
Rf2PDIF1 and Rf3PDIF2. Implementation of the
communication protocol IEC 61850 in these versions is
KEMA certified.

Software
IEC The data model of the measured operating values for
differential current and restraining current in the
functions DIFF and REF_x is now implemented
according to the data attributes for the standard WYE,
ACT and ACD classes.
Note:
With this implementation, the “phase” measured
values from the DIFF protection functions correspond to
the measured values of the three measuring systems:
●
“phSA” = Measuring system 1
●
“phSB” = Measuring system 2
●
“phSC” = Measuring system 3
Accordingly the measured values from the REF_x
protection functions are modeled as “neut”.
ICD and PICS-MICS-ADL files have been upgraded
accordingly.
