215   creat new LN for measurement function

Created: 23 Sep 2005

Status: Not Applicable

Part: Part 7-4 (2003)




Paragraph: 5.10.7

Category: Issue for edition 2 of this part


In 61850-7-4,there are MMXU,which used for currents,voltages,powers and impedances in a three-phase system. The type of its attributes: PPV,PhV,A, is DEL and WYE. In our application, we often deliver these data only with its mag and not with its angle. this is as same as ASDU_9 of IEC 60870-5-103.


I suggest that a new LN would be added in 61850-7-4 for delivering currents,voltages in a three-phase system with MV CDC attributes type.

Henry is correct. MMXU and 7-3 already provide this capability. Not Accepted...Move to final proposa 04 Oct 05 Ballot Period
In part 7-3 there is a description of vector (6.10), what is used for the three-phase values. Here the mag is mandatory, the ang is optional.
There is no need to create such a new LN.
