Interphase Spacers

Abstract

Line compaction is primarily based on the principle of minimising interphase spacing. As a result of this, and also since the interphase spacings are somewhat smaller than those encountered in the case of normal overhead transmission lines, there is greater risk of interphase flashover with a compact design when two conductors are moved close to one another, for example as a result of wind, ice shedding or short circuit; this may lead to an interruption in service. Interphase spacers (IPS) are used to avoid this. © Springer-Verlag Berlin Heidelberg 2013.
