Low confiability of transmision line
Low confiability of transmision line
(OP)
I work at a government's power utility company that is in charge of three areas: Generation, Transmision and Distribution, however, my area of work is distribution. The area of Transmision has been presenting a serious of apertures in the transmision line due to atmospheric discharges. The transmision line that brings electricity to the north coast of this country is a radial transmision line and we do not have another power line to back up in case the power line opens up (aperture). I need help as to how I may suggest ideas to my fellow transmision engineers to reduce the number of black outs that occurs everytime a power line is struck by lightning. Sometimes the substation relay is successful in doing the reclose but sometimes is not. Two years ago they grounded every tower and has helped a lot but not enough.

Conventional lightning rods do not avoid strikes, they just intercept them to safely carry the surge current to ground. The shield wire serves the same purpose.
There are "early streamer emission" (ESE) terminals that are claimed by their manufacturers to prevent strikes, but I believe the general consensus is that they do not work. Google "lightning ESE".
