Applications of fiber-optic cables with conductive support elements for installations on high-voltage line towers are not as common as all-dielectric cable designs. Therefore, influence of high-voltage lines on such cables was not widely studied. In this paper a lumped parameter model in phase coordinates was developed to determine the current and the voltage of a metallic element of a fiber-optic cable section installed on a high-voltage line. The methods necessary to determine the parameters of mutual induction and electrostatic links for this model was provided. A case study was performed for a figure-8 cable application on a 330 kV line, which indicated that the induced voltage to ground is the most significant threat to the cable if the conductive element is insulated from the ground. The demonstrated approach can be used for merit of analysis of high voltage line influence on any elongated conductive object.
