What is BS EN 50463-1-Energy measurement on board trains about?
BS EN 50463 is a European standard that discusses railway applications. BS EN 50463-1 provides the best industry guidance on energy measurement on board trains to build an efficient energy measurement system that provides reliable measurement and data that is suitable for billing and energy saving.
BS EN 50463-1 is the first part of a multi-part series that outlines 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, BS EN 50463-1 also describes the primary purpose of a DCS and its interactions with an EMS and settlement system.
BS EN 50463-1 is a standard that:
- Gives requirements for the complete Energy Measurement System and also requirements for all devices implementing one or more functions of the Energy Measurement System
- Applies to newly manufactured Energy Measurement Systems for use on board railway traction units, powered by AC. And/or DC. Supply voltages as listed in EN 50163
- Does not apply to portable Energy Measurement Systems
Who is BS EN 50463-1-Energy measurement on board trains for?
BS EN 50463-1 on energy measurement on board trains is useful for:
- Personnel or technical staff for energy measurement on board trains
- Regulatory authorities
Why should you use BS EN 50463-1-Energy measurement on board trains?
The Energy Measurement System provides measurement and data suitable for billing and may also be used for energy management, e.g., energy saving.
BS EN 50463-1 guideline assists you with system-level requirements on EMS operation, power supply, EMS measuring input, data handling, and RAMS for energy measurement on board trains.
BS EN 50463-1 guides on device-level requirements on marking of essential data, availability of essential data, interfaces, data processing, data transfer, software, software, environmental conditions, mechanical requirements, electrical requirements, construction, and design for energy measurement on board trains.
With compliance and obedience of BS EN 50463-1, you can build a suitable energy measurement system that provides reliable measurement and data suitable for billing and energy saving.
What’s changed since the last update?
BS EN 50463-1:2017 supersedes EN 50463-1:2012, which is withdrawn. BS EN 50463-1:2017 has extended the CPID definition (Clause 3 and Clause 4) compared to EN 50463-1:2012.
