System for reducing or clearing electrical AC field in room

摘要

The electric system has at least one electric field sensor allocated in the room. Also, at least one counter field generator (9), working depending on the signals from the field sensor, generating a counter field phase shifted 180 deg in the room (1). The counter field generator has an electrically conducting metal plate, provided with electrical insulation on the outside against contact, and is connected to an electric AC voltage supply. Alternatively another electrically conducting plate, a surface or a similar device.
