This graph compares the typical magnetic field for overhead power lines of different voltages. Typical fields are less than maximum fields because the current carried by a line is usually less than the maximum, and the clearance of the line above ground is usually more than the minimum. Select whichever comparison you want to see from the following:
typical magnetic fields | typical electric fields
maximum magnetic fields | maximum electric fields
You can also:
compare the fields from overhead lines and underground cables
see the field from any specific power line
see the field calculated for an actual sample of lines on the transmission system
see how far from the line the field falls to various values
see information on the direction of the field
