Abstract: This article investigates into ultimate capacities of location monitoring of 35–750 kV overhead transmission lines concerning detection of damages and ice deposits on wires. On the basis of theoretical and experimental location studies, minimum and maximum distances were evaluated at which short circuits and wire breakages could be detected, as well as minimum and maximum sizes of ice deposits on wires detected by location method. Daily and annual temperature variations of variables of reflected location signals are described. Sizes of ice coatings have been detected which cause tensile stresses in 35–750 kV overhead transmission lines. Maximum thickness of detectable ice walls on overhead transmission lines has been predicted and exemplified by existing overhead lines of Bugulma-110 substation, the detectable sizes exceed the ice wall thickness causing wire breakage.
