Which and how many IEC 61850 devices are successfully tested for conformance?

That's a good question ... that could easily be answered. Really! How? Let me explain:

The organization that is in charge for IEC 61850 conformance tests is the UCA International Usersgroup (UCAIUG). This organization has defined the test cases ... and issues certificates after a product has been positively tested by an authorized UCAIUG test lab like DNV.

The UCAIUG maintains a data base of certificates issued ... the data base has a lot of filter to search for some specific services a product supports. The following figure shows an excerpt of  a search for server devices that support IEC 61850-7-2 Setting Group Control services: 826 clients/server ... 656 server ...



Click HERE for the above search.

It takes some time to understand the filter and options ... it is a huge tool!!

Below is the filter for servers only (click on the link to the left):


To understand the details of the applied test cases, you have check with the UCAIUG test specifications ... example for Setting Group B4 and B4+ ...


1,682 devices (Client, Server, Merging Units, ...) have been tested positively ... they are listed in the data base.

Perfect! Drop me an email or post a comment to this post.

Enjoy.
