Profile
The working area of this working group includes realization, maintenance and dissemination of electric power and energy. To achieve this, the existing measurement methods are being permanently improved and new methods are being developed. Collaboration with national and international standardization groups and projects supports a constant exchange concerning actual requirements development in the field of electric power and energy measurement technologies.
Research/Development
- Development of new measurement procedures for calibration and test of precision measuring instruments for power and energy in the frequency range from 15 Hz to 10 kHz
- Development of new measurement procedures for testing and basic inspection of electricity meters
- Performance and efficiency measurements on the inductive charged bus system EMIL from Braunschweiger Verkehrs-AG
- Integration of PV storage systems for the own power use by using innovative measurement systems (PV storages)
- Data security und data integration by charging and billing of electricity in the field of electric mobility (DELTA) according to legal metrology / metrological customer protection
Services
Testing and/or calibration of standard electricity meters owned by the state approved test centers for electricity measurement, calibration authority and industrial calibration laboratories.
- Calibration and measurement capabilities of the division 2
