EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62888-1 test. IEC EN 62888-1 describes the primary purpose of the Energy Measurement System (EMS), which measures onboard energy consumption for energy management, energy conservation, billing and other applications.
It gives requirements for complete EMS, as well as requirements for all devices that implement one or more of the functions of EMS; Applies to newly manufactured EMSs for use in onboard traction units operating with AC or DC supply voltages as listed in IEC EN 60850.
The EMF provides a measurement of the consumed and regenerated active energy of a traction unit. If the traction unit is designed for use in AC traction supply systems, it also provides EMF reactive energy measurement. The EMF provides the measured quantities via an interface to the Data Processing System.
EMF consists of three functions: Voltage Measurement Function, Current Measurement Function and Energy Calculation Function. For each of these functions, accuracy classes are specified and associated reference conditions are defined. This section also defines all special requirements for all functions of EMF.
The Voltage Measurement Function measures the voltage of the ignition line (CL) system and the Current Measurement Function measures the current received and returned from the CL system. These functions provide signal inputs to the Energy Calculation Function.
The Energy Calculation Function inputs signals from the Current and Voltage Measurement Functions and calculates a set of values representing the consumed and regenerated energies. These values are transferred to the Data Processing System and used to generate the Compiled Energy Measurement Data.
This part of IEC EN 62888 provides requirements and guidance on data between functions implemented within the EMS, as well as between such functions and other embedded units where data is exchanged using a communication protocol stack over a dedicated physical interface or a shared network.
