This European Standard applies only to newly manufactured static energy meters of accuracy class 1, for the measurement on board, of alternating current electrical energy or direct current electrical energy used for traction applications operating at the following supply voltages: •25 kV (single phase) at 50 Hz, •15 kV (single phase) at 16,7 Hz, •3 kV, 1,5 kV and 0,75 kV d.c. It applies only to static meters consisting of a measuring element and register(s) enclosed together in a meter enclosure. It does not apply to: a)portable meters; b)data interfaces with on board systems; c)data management system; d)data interfaces with telecommunication system; e)on-board global measurement systems; additionally, if voltage and current transducers are considered of accuracy class 0,5. If these transducers are multi-service, specific and separate outputs will be considered.
