høyspentstrøm
Høyspentstrøm, also known as high-voltage direct current (HVDC), is an electrical power transmission system that uses direct current with a high voltage level. This technology is used to transmit large amounts of electrical power over long distances with minimal losses. HVDC systems are particularly useful for interconnecting asynchronous power systems, such as those in different countries or regions with different frequencies, and for transmitting power over long underwater cables.
The primary advantage of HVDC is its ability to reduce transmission losses compared to high-voltage alternating
HVDC systems typically consist of a rectifier at the sending end, which converts alternating current (AC) to
HVDC technology has been in use since the early 20th century, with the first commercial HVDC link
