  • Electrical appliance with reduced electric field emissions
    Patent number: 5506455
    Abstract: An electrical appliance comprises a power supply cable (70) having a first conductor (200) surrounded by a second conductor (210) for supplying electrical power to the appliance from a domestic electricity mains supply, and a connector (490) connected to cable for detachably connecting the conductors of the cable to first and second voltage signals of the electricity mains supply. In operation, the second conductor (210) is connected to the lower of the voltage signals. The second conductor (210) thus acts as a shield in opposition to electric fields radiating from the cable. The shield improves in efficiency as the lower mains voltage signal approaches Ground potential.
