Abstract: The device includes a current sensor connected to a supply line, a resistive voltage divider connected between the supply line and an electric earthing terminal, first processing devices connected to the current sensor and designed to generate signals or data indicating the intensity of the current drawn from the supply line, and second processing devices connected to the output of the voltage divider and designed to generate signals or data indicating the voltage of the supply line. The current sensor and related processing devices, as well as the voltage divider, are seated in a cavity inside a line insulator. The terminal with the lowest potential of the voltage divider is connected to a plate-like member made of electrically conductive material that extends outside the cavity of the insulator.

Abstract: A steering column arrangement including a steering column and a steering wheel, which is oriented at an angle to a horizontal, in which the steering column is connected to at least two pivoted levers, which each have a pivot bearing at both ends, the pivot bearings situated on the side of the pivoted levers remote from the steering wheel being fixedly attached, while the pivot bearings attached to the other end of the pivoted levers are arranged at a reciprocal distance from the steering column, the arrangement of the pivoted levers and the pivot bearings being selected so that under a force acting on the steering wheel in the direction of travel the steering wheel and steering column are moved simultaneously in the direction of travel and the steering wheel increases said angle.
