Nearby Power Lines
#17
This article details efforts some have made to tap into the E-field or H-field surrounding high-voltage transmission lines for "free" power.

The power companies can detect significant leakage and will investigate. It just shows that significant power is radiated from high-voltage lines, although it is primarily at 50/60 Hz, unless insulator arcing is causing signals to be radiated in higher RF ranges, like the old spark gap transmitters used by wireless CW Morse code operators before tube oscillators were invented.

50/60 Hz radiation should be handled by the filtering in the Blitzortung amplifiers. However, spark-generated RF is usually very broadband and can create intense radio receiver interference. I've had occasion to call the power company on several occasions to correct arcing insulators that were causing significant noise in the amateur radio shortwave bands. The FCC in the US requires the power companies to correct such interference. I have always received a prompt response to complaints, usually followed up with a detailed engineering report of the trouble found.
