Abstract:
A system for monitoring and warning regarding the presence of manually operated grounding contacts on high voltage conductors,characterized byan additional conductor (1) arranged close to and along at least part of a high voltage conductor (3) of interest, and adapted to be brought to physical/electrical engagement with said high voltage conductor (3) when a manually operated grounding contact is attached, said additional conductor (1) otherwise being fastened in an isolated manner relative to said high voltage conductor;a two-part, or elongate and externally isolated warning device (20; 20a, 20b) having a high voltage conductor proximal and a high voltage conductor distal warning part (20a, 20b) or end, said warning device being connected to both said high voltage conductor (3) and said additional conductor (1) in its conductor proximal warning part (20a) or end, and said warning device being adapted for optical or wireless transmission to said distal warning part (20b) or end, of a signal indicating possible physical/electrical engagement; andsignal transmission equipment (32) for transmitting said signal or a processed form thereof, from said distal warning part (20b) or end to a monitoring central (35).
