2021 is the European Year of Rail. On this occasion, CEN and CENELEC are proud to highlight the important role European standards play to ensure the well-functioning of a key sector for the future of Europe. Standardization on railways application is part of CEN and CENELEC’s wider work on transportation, a complex and large portfolio: it includes 1234 standards from CEN and CENELEC. These standards are mainly developed by two Technical Committees (TCs), CEN/TC 256 'Railway Applications' and CLC/TC 9X 'Electrical and electronic applications for railways'. In particular, standards on rail cover a wide range of topics specifically related to railways applications (products, processes and services), such as, among others, safety, rolling stock capacity, system efficiency, as well as cybersecurity, digitalisation, and automatic couplings. This work on rail contributes massively to the development of safe, innovative and efficient railway systems infrastructure, rolling stock and systems, and supports the EU in its strategic ambitions.
EMPIR MeterEMI project has released a report on current waveforms for static meter testing. In the report on the selection of recommended test waveforms for meters, in which is explained the rationale for the waveforms and methods used to accurately and efficiently specify these waveforms. In summary:
-
Most recommended waveforms are based on recordings on-site at real meter connection points. The waveforms have been simplified using a set of parameters, so they can be written down accurately and efficiently, suitable for inclusion in a future standard.
-
All recommended simplified waveforms have been generated on an arbitrary-waveform testbed and several produce gross meter errors on “faulty” meters similar to the original on-site recordings.
