Surge arresters are an essential aid to insulation coordination in electrical power supply systems. Valuable equipment can be protected against lightning- and switching overvoltages.
If basic rules are kept, modern Metal oxide surge arresters offer complete protection against overvoltages. In addition they offer a failure rate of nearly 0% and a lifetime of more than 20 years.
Costs of surge arresters in electrical power supply systems are less than 1% of the worth of the equipment they protect.
High availability and low costs of surge arresters facilitate new applications like surge arresters for transmission lines. As a result surge arresters convince with a quality improvement of electrical power supply systems.
