  1.  @robertgallagher7734  Yea, but 66KV is not that high... the noice issue is conected to what ever is near the wires, any vegetation or buildings will be affected by the reduced distance to the wires and then the leaks of energy to them are making this very specific sounds. "Voltages of 69 kV, 115 kV, and 138 kV are often used for subtransmission in North America" it is propably not some long distance line with higher voltages -> "The Western Interconnection has two primary interchange voltages: 500 kV AC at 60 Hz, and ±500 kV (1,000 kV net) DC from North to South (Columbia River to Southern California) and Northeast to Southwest (Utah to Southern California). The 287.5 kV (Hoover Dam to Los Angeles line, via Victorville) and 345 kV (Arizona Public Service (APS) line) are local standards, both of which were implemented before 500 kV became practical. "

  2.  @robertgallagher7734  CenterPoint Energy is using 69kV, 138kV and 345kV transmission systems...
