Information

Transmission line modelled as discretised telegraph-equation, 'pi-elements'.

The line of total length len is divided into elements of length delta = len/ne. It is composed of ne-1 interior elements of length delta and at each end of a half-element of length delta/2. Therefore it contains n interior nodes. Each element corresponds to a series inductor-resistor with values R and L corresponding to its length. A shunt parallel capacitor-conductor is liked to each node.
The minimum of ne is 1.

The fault is at relative length p(0< p< 1):

  p*len = distance to fault from terminal term_p

p is restricted in such a way that faults do not occur in the end-elements of the line. Furthermore the position within an element is restricted to a relative position between 0.1 and 0.9 for numerical reasons.
