IEC 61850 User Feedback Task Force

WG10 comment:
VRtg – ARtg – HzRtg: Similar to the other ones, this information should be part of the source to guarantee consistency of information, rather than having the same setting in
all of the P-logical node instances.
The question is how to be able to get this information and how to be sure that the information is in the CID file of the IED that needs the information. Possibilities: ExtRef with Poll method
RTE comment:
The use case here is different from NamAccRtg: it is not correct that these informations should be taken from TCTR/TVTR, since they correspond to the rated voltage / current of the
instrument transformer. For protections functions, the rated voltage and current of the corresponding feeder has to be used, and it may be different from the instrument transformers rating.

It is concluded that issue has to be presented and discussed on next joint meeting of TC57 & TC38 & TC95 in Lyon (May 25th, 2023). Will be presented by Maud Merley.
