  1. 1. Remote contact-free reconstruction of currents in two-dimensional parallel conductors

    Författare :Fatemeh Ghasemifard; Martin Norgren; Alessandro Formisano; KTH; []
    Nyckelord :Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis, the theory of the remote contact-free reconstruction of currents in two-dimensional parallel conductors is investigated. The motivation of this study is finding a complement technique to measurement transformers which are the well-established devices to measure currents in power transmission lines. LÄS MER
