The IEC 61850 Tissue Database is a very useful tool to help improving the quality of the standard series. The first Tissue (#1) was posted almost 19 years ago. On December 12, 2023 the Tissue #1900 was posted. In average two Tissues per week have been posted. The Tissue process is accepted all over.
The other day I received a question on the definition of power factor (MMXU.PF). The definition is contained in the Logical Node class MMXU of part IEC 61850-7-4:
When I read the definition I was wondering that there was no definition of the sign of the PF. I thought that somebody must have found this long before me ... I checked the Tissue Database to find the corresponding Tissue ... which is #1721 (Power factor related data objects in LN MMXU) dated September 22, 2020.
The following figure depicts the corrected definition.
