COMPUTATIONAL METHOD FOR POWER LINE MAGNETIC FIELD EVALUATION

Abstract

The paper reports a model for the power line magnetic field evaluation. The obtained results for three different power lines (380 kV double circuit,380 kV single circuit, 220 kV double circuit) was validated with measurement data. Calculated and corresponding measured data were found in good agreement. The influence of geometrical and electrical power line parameters, such as the spatial configuration of the conductors and line phase sequences, is evaluated and discussed. Data on the influence of adjacent line span on the field are also reported. The method can be used for prediction of human exposure in epidemiological studies.
