The meeting of EURAMET's Technical Committee for Electricity and Magnetism (TC-EM) and the subcommittees for Power and Energy and for Low Frequencies took place from 4 – 6 June 2025 in Lisbon, Portugal. One of the meeting highlights included the presentation of five joint research projects which shared their achievements with the TC:

e-TRENY: Metrology support for enhanced energy efficiency in DC transportation systems

The 22NRM04 e-TRENY project underwent its mid-term review in March 2025. A measurement campaign was conducted on Line 10B of Metro de Madrid as a joint effort involving INRiM (coordinator), Metro de Madrid, UNICampania , UNIGenova, and Systra France. Five measurement points were installed along the line, enabling synchronized voltage and current measurements. Simultaneously, electrical and mechanical quantities were recorded on board the train. The second measurement campaign, as outlined in the technical protocol, was launched at the Ustra substation in Hanover, Germany in May 2025. Data analysis is ongoing, with the goal of assessing the efficiency of electrical energy conversion and evaluating the impact of the reversible substation. Finally, two collaboration agreements have been signed with NIM and METAS.

ADMIT: Characterisation of MV instrument transformers in an extended frequence range up to 150 kHz

The 22NRM06 ADMIT began in June 2023 and the project mid-term meeting was held at LNE in Paris, France in December 2024. The measurement campaign is performed by monitoring the MV voltage and current level of the MV/LV (low voltage) secondary substation, a medium voltage high bandwidth termination has been installed in the cabinet. The deliverable D1 describing ‘performance requirements both for Instrument Transformers as well as for the measuring instruments connected to them, based on disturbances in AC and DC MV grids (system voltage < 36 kV) and on future measurement needs in the frequency range up to 150 kHz’, has been submitted in July 2025. The project is coordinated by the Italian national metrology institute INRiM and significant dissemination efforts have been carried out: to date, 10 papers have been published, and the project activities have been presented at six conferences. A measurement campaign has been performed in collaboration with UNIBO and UNICampania, thanks to Unareti S.p.a, an unfunded partner of the ADMIT Project, in “Ricevitrice Nord UNARETI” in Milan, Italy .

MetSuperCap: Metrology for static and dynamic characterization of supercapacitors

The 23IND04 MetSuperCap project started in June 2024. An ambitious measurement campaign has begun to characterise a large set of supercapacitors, which will be used to generate a public database. The project is coordinated by INRiM and has an overall objective: to establish a traceable, consistent and sound measurement and characterization framework for both supercapacitors (SCs) and SCs banks/modules. In March 2025 the first stakeholder meeting took place, and the mid-term meeting is under preparation in Delft at VSL on 5 – 6 November 2025. Anyone interested to be a stakeholder can contact the coordinator for participation on 6 November 2025. At the EMN Smart Grids meeting in Lisbon, Portugal in June 2025, the objectives and the first results, achieved during the first year, were presented including the identification of an equivalent circuit for the use in power systems.

Met4EVCS: Metrology for electric vehicle charging systems

The 23IND06 project Met4EVCS started in July 2024 and aims to address power quality issues related to electric vehicle charging systems (EVCSs) and evaluate metering reliability under on-site conditions. The project is coordinated by VSL and covers various charging modes and aims to develop a metrology infrastructure for traceable testing of EVCSs. Preliminary results on measurement approaches and first onsite measurements were presented at international workshops and research papers.

An online stakeholder workshop was held on 5 November 2024, with over 100 attendees from various stakeholders including EVCS and EV manufacturers, grid operators, academia, governments, standardisation bodies, and metrology organisations. A follow-up workshop will focus on on-site and laboratory measurements of EVCS distortions (conducted emissions and grid impedance up to 150 kHz) at the end of 2025 or early 2026.

Digital-IT: Metrology for digital substation instrumentation

The 21NRM02 project Digital-IT ended in August 2025. The final meeting was held in Borås, Sweden, on 17 – 18 June 2025 and work on-going with the deliverables, the consortium feel that they’ve accomplished what they originally set out to do. In WP1 many institutes have built new knowledge or fine-tuned existing capabilities for calibrating SV-enabled equipment, according to the requirements in IEC 61869. In WP2, new algorithms for extracting signal parameters from SV streams have been developed. And in WP3, three NMIs have developed their own method for providing traceable phase displacement calibrations for measurement equipment, which are synchronised by the PTP protocol. A comparison of the methods shows an agreement at a level well beyond what is required by accuracy specifications in relevant standards. The findings will be communicated to relevant standardisation bodies.
