Distribution voltages begin at 2,400 and go to 34,500 volts. Transmission voltages begin at ... depends upon the utility. Could be 46,000, 69,000 or 115,000.
Anyway... it's not the voltage. It's simply there is a device issue somewhere on a power line. Could be a bad connector. A bad transformer. A bad lightning arrester. A bad switch. A bad insulator. Bottom line, something is breaking down and creating this buzz. Begin by driving around the area and narrowing the area down. Then with a small yagi try to pin point things down to a few poles, or THE pole. Some electric companies have staff that can assist with RFI, and some do not. Don't assume they do. If you have questions, drop me a line. 73, Kim - WG8S
