The course is expected to be ready in Fall 2024. The frequency converter and conditions surrounding it are described, such that an understanding of the necessary electrical technical conditions is achieved for correct functioning and not emitting unwanted noise. Basic structure is looked at, which provides a background for the electrician to troubleshoot the installation. The necessary power grid conditions are also looked at, as well as the problem with high harmonic load from the power grid. 2, 6 and 12 pulse couplings are reviewed and compared with new motor controls which make a better load on the electricity grid. These may be a necessity to comply with requirements from the electricity supply company.
