This paper presents the results of laboratory tests of influence of the environment on pulses propagation conditions in the screen of coaxial cable. The reference level for the screen is the environment, which in real maintenance conditions, is the soil or it could be the inner work conductor. The objective of this work is to determine the possibility of using the pulse method for fault location of screen isolation of electric power cable line or telecommunication line. The special measurement system is described, which allows taking measurements of the influence of different substances types, which surround the location of damage, on the propagation of testing pulses. The results of measurements are shown in oscillograms obtained for typical substances which surround the cable in real exploitation conditions.
