Annex A (informative) Typical information given with
                      enquiries and tenders valid for
                      all types covered in this part of
                      IEC 61992
Annex B (informative) High voltage filters for protection
                      against voltage surges

Covers particular requirements for surge arresters for specific use in fixed installations of d.c. traction systems. They consist of one or more non-linear resistors which may be in series with single or multiple spark gaps. Covers also low-voltage limiters, that is protective devices mainly used in fixed installations of d.c. traction systems to connect certain portions of the circuit.
