Traceable measurement of supraharmonics

Important results from the project

Yes, the goals were met. The project developed traceable measurement technology and enabled evaluation of instruments, fully for 2–9kHz and partially for 9–150kHz. It also provided important synergies with other research projects, new contacts with manufacturers and laid the foundation for future work on calibration and measurement capabilities (CMC) and continued research.

Expected long term effects

The project is expected to have long-term effects through strengthened competence in supraharmonics measurement, opportunities to develop calibration and measurement capabilities (CMC), and increased ability to support industry and research actors. It also creates better conditions for future research collaborations and international standardization participation.

Approach and implementation

The project was carried out with lab work and development of the test bed as well as tests with power quality meters from four manufacturers. The activities were well organized and gave good results. The project did not develop completely according to plan as purchasing took longer and an unexpected need for equipment arose. The schedule was extended and more tests were done due to greater manufacturer interest than expected. The collaboration worked well.
