Related TISSUE:


IEC/TR 61850-7-5 Ed.1, clause 5.1.4, specifies that detailQual is not to be propagated. This statement was made having considered a couple of use cases. It is valid for all of these.

Now TC95 WG2 ask to consider the use case of phasors.
Phasors are calculated from sampled values. For the receiver of a phasor measurement is of relevance to know the detail quality provided with sampled values.
TC95 WG2 ask to re-consider the statement of clause 5.1.4 adding an exception for phasor calculation.
