Power Line Typologies and Elf Measurement Procedures

The issue of how to measure magnetic induction fields generated by various power line configurations, when there are several power lines that run across the same exposure area, has become a matter of interest and study within the Regional Environment Protection Agency of Friuli Venezia Giulia (ARPA FVG). In classifying the various power line typologies the definition of double circuit line was given: in this instance the magnetic field is determined by knowing the electric and geometric parameters of the line. In the case of independent lines instead, the field is undetermined. It is therefore pointed out how, in the latter case, extracting previsional information from a set of measurements of the magnetic field alone is impossible. Making measurements throughout the territory of service has in several cases offered the opportunity to define standard operational procedures. M. Benes, M. Comelli, A. Bampo, R.
