Metal Oxide Surge Arresters may represent an efficient choice for limiting lightning surges, significantly reducing the outage rate of overhead lines. The present work displays an analysis on the performance of gapless light-weight line surge arresters. The model recommended by IEEE is implemented in an FDTD model of overhead multiconductor lines by means of a local implicit scheme based on a set of non-linear equations. The model proves to ensure robustness and second-order accuracy.
