Parts

A technical issue - a tissue - is a question or a problem raised against one part of IEC 61850. Pick a part below to read the issues raised against it. The list shows when the most recent one arrived and how many there are in total.

How an issue is handled, from the first report to an agreed answer, is described in the Tissue Database User Guide.

The statuses an issue passes through, and the steps the workflow allows between them, are drawn in the workflow diagram, which opens in a new tab.
