Identification of Overhead Lines Using Measurements of the Electric Field Strength

The basis for creating a novel safety system for mobile building machines is laid after analysing building site accidents caused by mobile machines in the vicinity of overhead lines and examining currently used alert systems. This paper aims to provide a mathematical model to describe a two-stage collision zone around overhead lines and to ensure monitoring of the collision zone during construction work. A prerequisite for the description of the collision zone is the identification of the overhead line. An algorithm for the identification of overhead lines on the basis of electric field strength measurement is presented. The focus here is on measurement simulation and an analytical method that is used to identify the position of the conductors and the nominal voltage of the overhead line. The sensitivity of the algorithm is analysed.
