kilovolt per meter

Electric field strengthexact by definition

One kilovolt per metre, equal to 1000 V/m exactly. It is the unit of transmission-line and substation field exposure, where public-exposure limits and induced-voltage calculations are both written in these terms.

Where the unit came from

Field limits under high-voltage lines are set in kV/m because the numbers land conveniently: under a 500 kV line the ground-level field runs a few kV/m, and the ICNIRP public reference level is 5 kV/m at power frequency.
