scope:

This draft European Standard covers the requirements applicable to the Data Handling System of an Energy Measurement System, to be used onboard railway traction units for the measurement of energy taken from or returned to the Contact Line system. The Data Handling System receives, produces and stores data, ready for transmission to any authorised receiver of data on-board or on-ground. The main goal of the Data Handling System is to produce Compiled Energy Billing Data and transfer it to an on-ground Data Collection Service. The Data Handling System can support other functionality onboard or on-ground with data, as long as this does not conflict with the main goal. This document also includes the Essential Requirements for the Data Collection Service on-ground, relating to the aquisition and storage of Compiled Energy Billing Data. The Conformity Assessment arrangements for the DHS are specified in this document.
