EN 50152-2:1997

EN 50152-2:1997 is a standard published by CLC. Its full title is "Railway applications - Fixed installations - Particular requirements for a.c. switchgear - Part 2: Single-phase disconnectors, earthing switches and switches with Um above 1 kV". This standard covers: This part of EN 50152 is applicable to single-phase a.c. one-pole disconnectors, earthing switches and switches (switch-disconnectors and general purpose switches) designed for indoor and outdoor fixed installations for operation at frequencies of 16 2/3 Hz and 50 Hz on traction systems having an U Nm above 1 kV up to 52 kV. This standard is also applicable to two-pole disconnectors, earthing switches and switches (switch-disconnectors and general purpose switches) connected in the following manner either: one-pole supplying the connection to the contract line of the track, the other supplying the connection to the feeder cable which runs alongside the same track and is used to boost the track voltage at regular intervals in combination with autotransformers; or the two poles of the disconnector, earthing switch or switch (switch-disconnector or general purpose switch) are connected in series to provide secure isolation (ie two breaks in series)
