High Voltage (13kv) Power Site, CCTV And Wireless Transmission

Have anyone dealed with such scenario?

(http://en.wikipedia.org/wiki/Electrical_substation).

I've heard from an installer that they never had special problems using analog/coax in the perimeter, some like 50 meters away from the high power devices, but this is just a non-verified reference.

Thanks.


The country is Venezuela, were applies the same electrical US codes.

Distances from cameras to power devices goes from 5 to 100 meters.
