CLC/TC 9X/WG 37 - Survey Group on "Energy measurement"

EN 50463-4 applies to the on board and on board to ground communication services. EN 50463-4 covers the data communication using digital interfaces between functions implemented within the EMS, between EMS function and other on-board subsystems and between EMS and ground communication services.

EN 50463-5 specifies the conformity assessment arrangements for newly manufactured EMS installed on a traction unit. This includes the integration conformity assessment and installation conformity assessment. In addition, EN 50463-5 also specifies the conformity assessment procedures for device and ancillary component replacement (e.g. due to damage in service), and periodic check to verify the EMS conformity assessment remains valid.

EN 50463-2 covers the requirements applicable to the Energy Measurement Function (EMF) of an Energy Measurement System (EMS) for use on board traction units for measurement of energy supplied directly from/to the Contact Line system. EN 50463-2 also gives requirements for the Current Measurement Function (e.g. current sensor), the Voltage Measurement Function (e.g. voltage sensor) and the Energy Calculation Function (e.g. energy meter).

EN 50463-1 describes the primary purpose of the EMS, which is to meter energy consumption for billing and provide compiled energy billing data (CEBD) to a DCS. The EMS may also be used for other functions such as energy management. In addition, EN 50463-1 also describes the primary purpose of a DCS and its interactions with an EMS and settlement system.
