MT 62888 - TC 9/MT 62888

IEC 62888-2:2018 specifies 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. This document 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).

IEC 62888-3:2018 covers the requirements applicable to the Data Handling System (DHS) of an Energy Measurement System. This document also includes the basic requirements for the Data Collection Service on ground, relating to the acquisition and storage of Compiled Energy Measurement Data.

IEC 62888-1:2018 describes the primary purpose of the Energy Measurement System (EMS), which measures energy consumption on board for applications such as energy management, energy saving, billing and others. It gives requirements for the complete EMS and also requirements for all devices implementing one or more functions of the EMS; applies to newly manufactured EMSs for use on board traction units, powered by AC and/or DC supply voltages as listed in IEC 60850.

IEC 62888-4:2018 applies to the on board and on board to ground communication services, i.e. it covers the data communication using digital interfaces:
a) between functions implemented within the EMS;
b) between EMS function and other on board subsystems;
c) between EMS and ground communication services.
