Link

A link is the model for a connection between two nodes, which has close to zero impedance.

 

A link can only be applied if the nominal voltages of both nodes are equal.

 

 

PARAMETERS

 

General

In this form the switches on both sides of the connection can be opened or closed.

 

Parameter

Description

Name

Name of the connection

Subnet border

Division of parts of the network which are fed through different transformers or sources

From-node

Name of the node from which the cable is connected

To-node

Name of the node to which the cable is connected

 

The link runs from a From-node towards a To-node. The From-node and To-node can be exchanged by using the button: <>.

 

Ampacity

A Link has a rated current Inom and a maximum short-circuit current Ik(1s). If specified, the loading will be presented in the results. If not specified, the link is assumed to be infinitely strong and its loading will not be shown.

 

Connection

The connection of a link to a busbar system can be defined on the tab Connection as:

rail selectable,

not rail selectable or

fixed.

This only affects the graphical representation.

 

Impedances

The impedances of the link are adjustable in the options, in Calculation | General. The possible values are:

R, X, R0 and X0 = 1 µΩ tot 10 mΩ
