Version Changes
IEC The data model of the measured operating values for
differential current and restraining current in the DIFF
function 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 function correspond to
the measured values of the three measuring systems:
●
“phSA” = Measuring system 1
●
“phSB” = Measuring system 2
●
“phSC” = Measuring system 3
ICD and PICS-MICS-ADL files have been upgraded
accordingly.
