.PowerSystems.AC3ph.Lines.PIline .PowerSystems.AC3ph.Lines.PIlineTransmission line modelled as discretised telegraph-equation, 'π-elements'.
The line of total length len is divided into elements
of length delta = len/ne. It is composed of ne
interior elements of length delta. Therefore it contains
ne+1 nodes. Each element corresponds to a series
resistor-inductor with values R and L corresponding to its length.
A shunt parallel capacitor-conductor is linked to each node.
The minimum of ne is 1.
