Abstract
A method for monitoring of condition of a cable conduit, in particular a corrugated cable conduit, comprising the following steps: detecting (101A1) values of relative concentration of gas with variable concentration Rx<sub>in(i)</sub> inside a cable conduit (1) in a preset time window and creating (102A1) time series of the values of relative concentration of gas with variable concentration Rx<sub>in(i)</sub> inside the cable conduit (1), wherein each of said values has an assigned timestamp or each of said values is detected (101A1) with a predefined sampling rate, where i = (1, 2, ..., n); detecting (101A2) values of relative concentration of gas with variable concentration Rx<sub>out(i)</sub> outside the cable conduit (1) in the preset time window and creating (102A2) time series of the values of relative concentration of gas with variable concentration Rx<sub>out(i)</sub> outside the cable conduit (1), wherein each of said values has an assigned timestamp or each of said values is detected (101A2) with the predefined sampling rate, where i = (1, 2, ...,n); wherein the detection (101A1) of the values of relative concentration of gas with variable concentration Rx<sub>in(i)</sub> inside the cable conduit (1) and the detection (101A2) of the values of relative concentration of gas with variable concentration Rx<sub>out(i)</sub> outside the cable conduit (1) is synchronized; determining (109) a correlation coefficient based on the values of relative concentration of gas with variable concentration Rx<sub>in(i)</sub> inside the cable conduit (1) from the created (102A1) time series and on the values of relative concentration of gas with variable concentration Rx<sub>one(i)</sub> outside the cable conduit (1) from the created (102A2) time series, where i = (1, 2, ...,n); assessing (110) condition of the cable conduit (1) by comparing the determined (109) correlation coefficient to a threshold value such that when said correlation coefficient exceeds the threshold value, the cable conduit (1) is considered non-hermetic.
