This website deals with the electric and magnetic fields produced by the use of electricity including the electricity transmission and distribution systems - power lines, substations etc.
We recognise that people often have other questions about power lines and substations. We can't provide detailed or authoritative answers to these non-EMF questions but we provide some pointers here to where you can find out more.
