注意区别高压线和一般输电线的区别
高压线：high voltage transmission lines
Electrical energy from generating stations is distributed to communities via high voltage transmission lines. Transformers are used to lower the voltage for connections to residential distribution lines that deliver the energy to homes. Electric and magnetic fields underneath overhead transmission lines may be as high as 12 kV/m and 30 µT respectively. Around generating stations and substations, electric fields up to 16 kV/m and magnetic fields up to 270 µT may be found.

舞秋月，俏江风，也是疏狂，也任真！ |
