scope:

This European Standard applies only to newly manufactured static energy meters of accuracy class 1 or higher, for the measurement of alternating current electrical energy or direct current electrical energy used by trains for following power supply: - 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.
