30、nverter transformer (K 1)28 EN 50327:2003 - 4 - Introduction Converters, traction transformers and switchgear are ordered in most cases as individual items and are tested in manufacturers premises as such. It is evident that tuning is necessary to choose compatible ratings and that certain performan
31、ces cannot be verified (through additional or investigation type tests) unless at least the traction transformer and the converter are coupled together. That is the reason for this document. - 5 - EN 50327:2003 1 Scope This European Standard provides requirements for some type tests which are signif
32、icant only when made on the entire group. It provides also a basic relationship between compatible ratings of traction transformer and converter(s), in order to provide minimum requirements for the choice of their ratings. Moreover it gives the minimum values to be considered in order to choose swit
33、ching devices with characteristics suitable for the converter group(s) involved. Annexes provide useful information as a guide for the group designer.
