This standard establishes uniform procedures for the measurement of power frequency electric and magnetic fields from alternating current (ac) overhead power lines and for the calibration of the meters used in these measurements. A uniform procedure is a prerequisite to comparisons of electric and magnetic fields of various ac overhead power lines. These procedures apply to the measurement of electric and magnetic fields close to ground level. They can also be tentatively applied to electric field measurements near an energized conductor or structure with the limitations outlined in 3.5. The purpose of this standard is to establish uniform procedures for the measurement of electric and magnetic field levels from overhead ac power lines, and to establish calibration procedures for the meters used in these measurements. A uniform measurement procedure with established instrumentation and calibration is a prerequisite to comparisons or validation, or both, of the electric and magnetic field strength associated with various overhead power lines. Revision Standard - Active. Uniform procedures for the measurement of power frequency electric and magnetic fields from alternating current (ac) overhead power lines and for the calibration of the meters used in these measurements are established in this standard. The procedures apply to the measurement of electric and magnetic fields close to ground level. The procedures can also be tentatively applied (with limitations, as specified in the standard) to electric fields near an energized conductor or structure.
