Interaction of Line Surge Arresters with Vibration Dampers

Transmission line surge arresters have become an important design and mitigation alternative to improve grounding and reduce investment in overhead ground wire. However, they can experience a number of mechanical problems, including degradation of components associated with flexible leads. Read More >

Benefits Justify More Use of Transmission Line Arresters

Application of gapped or non-gapped transmission line surge arresters offers perhaps the best opportunity to improve reliability of power systems. However, the value of using them transcends this single objective since they also offer many additional benefits. Read More >
