Innovative SF6 free switch with shunt vacuum interruption technology

This paper presents an innovative and compact SF6 free switch with shunt vacuum interruption (SVI) technology. To replace SF6 as arc-quenching gas, some alternative fluorinated candidates were identified for medium voltage electrical equipment. …

A new approach in computing the effects of high harmonic currents generated by power electronic components in the grid on the transformer winding losses

In this paper a 2D finite element numerical simulation method by considering the geometrical model of the real transformer core and windings is proposed to accurately compute the magnetic stray fields and corresponding effects…
