    Sammanfattning : Recent research demonstrated that polymer based nanocomposites (PNCs) have been engineered in order to improve the arc interruption capability of the circuit breakers. PNCs are the combination of nano-sized inorganic nanoparticles (NPs) and polymers, opened up new developments in materials science and engineering applications. LÄS MER

  3. 2. Ultra-fast electromechanical commutation switch for hybrid breakers

    Författare :Mrunal Parekh; Marley Becerra Garcia; Christian Franck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In a power system with the ability to integrate geographically spread diverse renewable energy sources, there is a need for efficient control of the power flow and effective power transmission. Power electronics can provide this controllability, at the expense of conductive losses in the used components. LÄS MER
