The representative of the Directorate for Measures and Precious Metals, Jasmina Lazarevic, metrologist for alternating voltage and current in the Group for Electrical Quantities, participated on June 6, 2025 in the work of the EURAMET subcommittee for low frequencies of the Technical Committee for Electricity and Magnetism (EURAMET SC-LF), which this year was held hybridly in Lisbon, Portugal.

The organizer of the meeting was the National Metrological Institute of Portugal (IPQ). The meeting was attended by 60 representatives of national metrology institutes (NMI).

Notable topics presented were current and completed AC power projects, impedance measurement bridges, coaxial air duct as a low frequency impedance reference, and diamond chip resistor used in PMJTCs (planar thermal converters).

Ongoing projects are presented, such as the AC-DC transfer calibration guide project and the digital multimeter calibration guide, and suggestions and initiatives for new projects are expected.

At the meeting of this subcommittee, the status of existing CMCs and the application of future CMCs, news in the work of EURAMET, the status of key and supplementary comparisons, the planning of new ones, as well as ideas and plans for future activities were discussed.
