[Elecraft] [OT] Ham Radio near high voltage power lines?

[N4ZR]

I recall reading on the RFI reflector that HV transmission lines are 
rarely a problem, or at least not for long, because power companies lose 
real money when power leaked, so they had a strong incentive to repair 
problems as soon as possible.

I have two 500 kv transmission lines that run beyond the entire west 
edge of my property about 200 feet away, and a 7500-volt secondary 
distribution line in an easement right on the property line. Initially I 
thought one or both was giving me trouble, but I took a 136-MHz DF rig 
out there and established, to my satisfaction, that the transmission and 
the distribution line were not the problem.  At least in this vicinity, 
a far bigger problem is old distribution hardware - transformers, 
lightning arrestors and so on, which the power company plans to attack 
wholesale next week.  It will be interesting!
