- Abstract:
- Measurements of electromagnetic fields in the vicinity of overhead power lines are carried out in order to assess the exposure of the general public to these fields and to check whether the field levels are within the prescribed limits. Since the measurement results are compared with the prescribed reference levels, the measurement uncertainty should be evaluated and taken into account in the conformity assessment. The paper analyzes the most relevant uncertainty components related to measurements of electric and magnetic fields near overhead power lines. The uncertainty components related to the calibration of the measuring system, proximity of the operator and positioning of the measuring probe are analyzed and evaluated for the real example of measurements near an overhead power line. In order to provide the validity of the measurement results the measurements are carried out with two measuring systems and they are also compared with the calculation results.
