Abstract: In the case of parallel and narrow high voltage aerial power lines, where one of the circuits is disconnected, knowing the electric and magnetic coupling mechanisms and the values of the voltages induced by the respective types of couplings at low frequencies is very important for finding the methods and means of warning and protecting the working staff involved in the maintenance programmes on these routes. The paper presents the measurements that the author has done in the south - western area of Romania for the 220 kV double circuit aerial power lines having a passive circuit and an active one. It also describes a mathematical simulation for determining the voltages induced by the active circuit into the disconnected circuit of the power lines, accompanied by a calculating programme of these voltages. The results of the measurements are compared with those obtained through calculations. Thus the mathematical simulation is validated turning it into a useful instrument for electric power specialists.
