Parameters
Wires are graphical lines used to interconnect component instances together on the PSCAD Circuit canvas. A wire can carry an electrical signal, in which case it acts to electrically connect nodes together. A wire may also be used as a data signal pathway, where a connection between two data points forces connected points equal to one another. Wires can be added manually to the canvas as described in Adding Components to a Project and Connecting Components Together, or drawn using Wire Mode.
A Wire is a 'stretchable component', that is its length may be altered to fit the required use. Wires can be connected together by ensuring that an endpoint of one of the joined wires is touching any part of the other wire. Wires can be crossed (or overlapped) without a connection, so long as neither the endpoints nor vertices are touching the other Wire. Wires can also consist of multiple, orthogonal segments, where the entire wire can be manipulated as a whole.
Both electrical and data signals carried by a wire can be multi-dimensional, that is the signal may be passed as an array (vector). PSCAD will automatically detect what type of signal is to be passed, as well as the dimension of the points to which the Wire is connected.
