Railway applications - Energy measurement on board trains - Part 5: Conformity assessment

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.

Railway applications - Energy measurement on board trains - Part 1: General

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.

Railway applications - Energy measurement on board trains - Part 2: Energy measuring

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).
