AMOP:
The AMOP program calculates weakening of the signals transmitted by carrier wave of high voltage lines and extra high voltage. Using modal analysis, and obtained for all possible combinations of pairs of sending and receiving phases, and for each frequency studied the relationship between the signal and the received signal.
Transpositions into account along the path and the terrain variations in resistivity along the line.
It also allows the analysis with parallel lines, and cases of failure (phase short circuit).
