DIN EN 50463-1:2013-06

The primary purpose of the Energy Measurement System (EMS) is to meter energy consumption for billing. It may also be used for other functions such as energy management. The standard series DIN EN 50463 describes the EMS by using a functional approach. This first part DIN EN 50463-1 provides system level requirements for the complete EMS and common requirements for all devices implementing one or more functions of the EMS. This European Standard applies to newly manufactured EMSs for use on board railway traction units, powered by a.c. and/or d.c. supply voltages as listed in DIN EN 50163. It does not apply to portable EMSs, however. The responsible committee is K 351 "Elektrische Ausrüstungen für Bahnen" ("Electrical equipment and systems for railways") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
