Tasks:

Maintenance and development of standards and measurement facilities of electric and magnetic quantities.
Transfer of electric and magnetic quantities measures units maintaining the traceability by performing calibrations of measurement equipment for interested entities (e.g. regional administration of measures, measuring laboratories,  industry).
Conformity assessment tests of electric energy meters,
Electromagnetic compatibility (EMC) tests for conformity assessment and type approval of measurement equipment being subject to legal metrology control.
Research and development work related to electrical metrology,
Development and implementation of innovative measurement methods for particular electric and magnetic quantities.
Organization and leading interlaboratory comparisons and participation in international comparisons.

Services:
