High voltage surge arrester type 1 Siemens PTD High Voltage
230/400 V - 52 kV

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.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 the result Surge Arresters convince with a quality improvement of electrical power supply systems.
