Power lines, three-phase and high-tension, in my experience do not have any
impact on GPS reception nor on the internal working of the receiver unless
your are in very close proximity of 10-15 meters. Microwave radiation on
the other hand does impact most GPS devices. You might want to check into
microwave signal channels passing over your areas of interest.

Subject: GISList: GPS by high power lines
Had a field worker using a Garmin GPSMap 76 report that it didn't work
near
high power lines, which I found hard to believe. Anyone else have
specific
experience about them not working in such areas, or more general tips
about
where they don't work besides usual (heavy canopy).
