The present invention concerns a method for determining a length quantity of a power transmission line, wherein the power transmission line connects a first location with a second location, wherein the method comprises: providing a first signal having a first carrier frequency (f1) at the first location; transmitting the first signal from the first location to a second location via the power transmission line; providing a second signal having a second frequency (f1') at the second location; measuring a first phase difference between the first signal and the second signal at the second location; calculating the length quantity from the measured phase difference. Further, the invention concerns a system for determining the length of a power transmission line (130) between a first location (110) and a second location (120), wherein a second receiver at the second location is adapted to receive a first signal having a first carrier frequency (f1) from the first location, wherein the system comprises an frequency generator (122) for creating a second signal having a second frequency (f1') at the second location; wherein the receiver further comprises a phase detection device (126) adapted for detecting a first phase difference between the second frequency and the first carrier frequency at the second location.

La présente invention concerne un procédé destiné à déterminer une grandeur de longueur dune ligne de transport délectricité, la ligne de transport délectricité connectant un premier emplacement à un second emplacement, le procédé consistant à : fournir un premier signal ayant une première fréquence porteuse (f1) au premier emplacement; transmettre le premier signal du premier emplacement à un second emplacement par lintermédiaire de la ligne de transport délectricité; fournir un second signal ayant une seconde fréquence (f1') au second emplacement; mesurer une première différence de phase entre le premier signal et le second signal au second emplacement; calculer la grandeur de longueur à partir de la différence de phase mesurée. De plus, linvention concerne un système permettant de déterminer la longueur dune ligne de transport délectricité (130) entre un premier emplacement (110) et un second emplacement (120), un second récepteur qui se trouve au second emplacement étant conçu pour recevoir un premier signal ayant une première fréquence porteuse (f1) en provenance du premier emplacement, le système comprenant un générateur de fréquence (122) destiné à créer un second signal ayant une seconde fréquence (f1') au second emplacement; le récepteur comprenant en outre un  dispositif de détection de phase (126) conçu pour détecter une première différence de phase entre la seconde fréquence et la première fréquence porteuse au second emplacement.
