One of the objectives of this website is to share information about the definition and use of the International Standard IEC 61850. Collecting, logging, presenting and solving technical issues (tissues) is supported by this website.

A technical issue – a tissue – is a question or a problem raised against one part of IEC 61850: something in the standard that is unclear, contradictory or wrong. Tissues are collected here, discussed by the working group responsible for that part, and given an agreed answer, which stays with the tissue for anyone to read afterwards.

Reading needs no account. Anyone can open the list of parts, read the tissues raised against each one and follow the discussion. A free account is needed only to raise a tissue, to comment on one, or to subscribe to a part and be sent a weekly summary of what changed in it.

You can also find some of the latest news in the news section.
