Railway applications - Fixed installations - D.C. switchgear -- Part 5: Surge arresters and low-voltage limiters for specific use in d.c. systems

Divisions 1, 2, 3 and 4 of EN 50123-5 cover particular requirements for surge arrestors for specific use in fixed installations of d.c. traction systems. These are surge arresters consisting of one or more non-linear resistors which may be in series with single or multiple spark gaps. Low-voltage limiters are covered under division 5 of EN 50123-5. These are protective devices mainly used in fixed installations of d.c. traction systems to connect certain portions of the circuit, when, owing to an abnormal situation, the voltage across the device exceeds a predetermined limited value. They are not used in general to provide surge protection
