Abstract
The electricity distribution network comprises a plurality of interconnection lines for the distribution of electricity among a plurality of interconnection boxes. At least some of said interconnection boxes are combined with a control unit for detection of stray voltage, comprising a transmitter to transmit to a receiver of at least one collecting unit a signal relating to any dispersion.
Claims55
An electricity distribution network comprising a plurality of interconnection lines for the distribution of electricity among a plurality of interconnection boxes which are provided with a cover portion exposed on a road surface, wherein at least some of said interconnection boxes are combined with a stray voltage control unit connected at least to a portion of the box liable to cause accidents in the event of a stray voltage being present on said portion, said control unit including a transmitter to transmit to a receiver of at least one collecting unit any stray voltage signal when said portion of the box is energized at a hazardous voltage, and wherein said control unit and said at least one collecting unit communicate via carrier waves on said interconnection lines.
An electricity distribution network comprising a plurality of interconnection lines for the distribution of electricity among a plurality of interconnection boxes which are provided with a cover portion exposed on a road surface, wherein at least one of said interconnection boxes is combined with a stray-voltage control unit, said stray-voltage control unit including a transmitter to transmit a stray voltage signal when a hazardous voltage is detected on at least one portion of said box, and wherein said stray voltage signal is transmitted via carrier waves on at least one of said interconnection lines.
An interconnection box including a cover portion designed to be arranged on a road, an aperture, a removable cover closing said aperture and at least one electricity distribution line entering said box, wherein:
- a stray voltage control unit is arranged at said interconnection box;
- and said stray voltage control unit includes a stray voltage detection device arranged to detect a stray voltage on at least one portion of said interconnection box and a transmitter to transmit an information on said stray voltage on said electricity distribution line.
