  • Apparatus for measuring the electrical energy delivered to a rail traction unit by a high voltage line
    Patent number: 7800355
    Abstract: Apparatus for measuring the electrical energy supplied to a rail traction unit by a high voltage line (1), the apparatus comprising measurement means (5, 26) for measuring the current drawn, and measurement means (12, 27) for measuring the voltage of the power supply, said measurement means themselves possessing a low voltage power supply (23, 24) necessary to enable them to operate, the apparatus being characterized in that the low voltage electrical power supply is taken from light energy converted (22) into electrical energy.
    Type: Grant

  • Electric railway vehicle and an electric powering unit in particular for such a vehicle
    Patent number: 6371265
    Abstract: An electrical power supply unit powers a load, in particular a transformer (8), from a power source (10) via electrical switchgear (14), in particular a circuit-breaker, and it includes an interference attenuator (16) of the ferrite type for attenuating interference due to switching. The attenuator (16) is placed between the power source (10) and the electrical switchgear (14), thereby contributing to reducing the extent of the interference significantly.
