Abstract

An integrated system to evaluate the magnetic field generated by power lines exposure has been developed using a specific simulation model (PLEIA-EMF). This is part of a software toolset, subjected to internal suitability verifications and in-field validations. A state indicator related to each span has been determined using the data extracted from digital cartography, the magnetic field calculated by PLEIA and the number of people living in the nearest buildings. In this way, it is possible to determine eventual criticalities in the considered area, focusing attention on those cases with more considerable exposure levels and involving a higher number of people. A campaign of inspections has been planned using PLEIA simulations. The reliability of stored technical data and the real population exposure levels have been evaluated in critical cases, individuated through the following described methodology. The procedures leading to the indicator determination and the modalities of in situ inspections are here presented.

Main findings

The authors describe an integrated system using a simulation model (PLEIA-EMF) and digital cartography to calculate magnetic fields from power lines and combine these with nearby population counts to create a span-level state indicator. The indicator is intended to identify potential criticalities and prioritize in situ inspections; inspections were planned using simulations and used to evaluate reliability of technical data and population exposure levels in selected critical cases.
