22. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. READ MORE
