Measurement of DC energy has always been one of the most important areas of development in our company. Thanks to the efforts of our skilled engineers, we have launched the third generation of the EM3000 electric energy meter. In addition to updating the design and adapting it to new standards and guidelines, we have created an improved and expanded version of the EM3000 meter, capable of measuring energy in both DC and AC networks.
The multisystem EM3000 electric energy meter is an innovative, comprehensive solution designed for measuring traction energy in DC 1.5kV and 3kV systems, as well as AC 15kV 16 2/3 Hz and 25kV 50Hz systems. It meets the TSI LOC&PAS requirements, including updates up to 2020/387, a set of European standards including EN50463:2018, and the current "PKP Energetyka Requirements for DC Energy Measurement Devices" outlined in the Distribution Network Operation and Maintenance Instruction, unified text effective December 15, 2021.
Key Features of the Multisystem EM3000 Meter:
Full Autonomy: The HVU measurement section is directly powered by the measured voltage, ensuring no loss of measurement capability even during auxiliary power supply outages.
Flexible Configuration: Multiple HVU measurement sections can be connected to a DHU communication module, enabling the EM3000 to function as a comprehensive DC energy measurement solution for an entire EMU or locomotive (multiple units/load points) and facilitating the construction of a multisystem measurement setup.
Power Supply Options: The EM3000 modules can be powered by voltages of 24V DC, 48V DC, or 110V DC, depending on the configuration.
Applications:
Onboard Use:
Locomotives
Electric Multiple Units (EMUs)
Trams
Trolleybuses
Stationary Installations:
Buildings (e.g., traction substations)
Pole-mounted installations (e.g., for wagon heating, 3kV DC/400V AC converter stations, or non-railway consumers).
Functions:
Automatic switching between measured traction systems.
Measurement of consumed and regenerated energy.
Measurement of active and reactive energy.
Registration of energy in 5-minute (CEBD settlement) and 1-minute (statistical) cycles.
Registration of energy consumption locations (GPS) in a 1-minute cycle.
Time-zone-based energy registration according to a defined tariff.
Event logging.
Measurement and logging of current and voltage.
Wired communication with onboard traction vehicle systems.
Data transmission to energy supplier and carrier acquisition systems via two independent GSM/3G/LTE modules.
Local data reading via an LCD touch panel.
Self-diagnostics.
EM3000 Components:
DHU (Data Handling Unit): Communication unit integrating two modules from EM3000 v2 (low-voltage and MK modules) with a built-in surge protection module.
DHU Module
HVU – High Voltage Unit DC: The measurement unit of the EM3000 meter designed for DC voltage systems. Available configurations include 600V DC, 750V DC, 1.5kV DC, or 3kV DC.
HVU Module
EMU AC – Energy Measurement Unit AC: A measurement unit capable of handling AC 15kV 16 2/3 Hz, AC 25kV 50 Hz, DC 3kV, and DC 1.5kV systems. It performs indirect current and voltage measurements via transformers and is compatible with transformers from leading railway manufacturers such as S.T.E., RITZ, LEM, and SECHERON. Existing transformers installed on vehicles can also be utilized, provided they meet relevant standards, hold required certifications, and achieve the necessary accuracy class.
EMU AC Module
SIG – Signalization Unit: An optional signaling module within the EM3000 system, controlled by the EMU module.
SIG Module
EM3000 F+D: A sealable overcurrent protection device with signaling, serving as an optional component of the EM3000 system.
