Abstract: Device for measuring the electric power drawn by a railway vehicle from a high-voltage electric supply line including a current sensor connected to the supply line, a resistive voltage divider connected between the line and earth, first processing devices connected to the current sensor, second processing devices connected to the output of the voltage divider. The current sensor, related processing devices and 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 conductive member that extends outside the cavity of the insulator. A hollow conductive body, connected to earth contains the second processing devices and is connected to the lower end of the insulator. It includes a wall arranged opposite the member to form a discharger with it.
