User interface > Edit components > Special, Subnet border

The automatic determination of suspected grid dividing limits.

Subnet borders separate parts of the network that are fed by different sources or transformers.

To automatically determine possible subnet borders, a route is determined from each mains supply and from each transformer.

To be identified as a subnet border:

•all branches of which one switch is open and the node on the other side is fed:

▪by another mains supply or

▪by another transformer.

The form shows three lists with branches:

Potential subnet border: branches that are now not classified as a subnet border, but probably are

Not plausible subnet border: branches that are now classified as a subnet border, but probably are not

Plausible subnet border: branches that are now regarded as a subnet border and that probably are

In the three lists, it is also indicated which are the two feeding nodes on both sides of the branch.

When leaving the form with OK, the subnet border of branches shown is set according to the check marks.

The names of the feeding nodes are also included in the relevant two parameters of the branch.
