Application:Surge Arresters for DC traction systems
The metal-oxide surge arresters for DC traction systems are developed and type tested according to the new European standard EN 50526-1 which is specifically for metal-oxide surge arrester in railway application up to 3kV nominal voltage. The surge arresters also meet the requirements for A1/A2 functionality according to VDV 525 recommendation.
The rails of DC traction systems are isolated from earth to avoid stray currents in the ground. Voltage limiting devices are being used to avoid unacceptable touch voltages during operation and in fault conditions.
The voltage limiting device is a hybrid composed by a metal-oxide surge arrester connected in parallel with thyristors. Dangerous transient over-voltages from lightning and switching are limited by the surge arrester. Longer lasting over-voltages from the traction system are limited by the thyristors after triggering.
