Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 479-498, August 2026.During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing
High Voltage, Volume 11, Issue 4, Page 975-986, August 2026.ABSTRACT During long‐term operation of converter transformers, the internal oil–pressboard insulation undergoes irreversible degradation. Partial discharge in the weakened insulation will cause the formation of a large number of bubbles in the insulating oil.

High pulse AC/DC convertors and their application to HVDC transmission. [PDF]
, 1992 AC/DC convertors used in HVdc transmission systems inject harmonics into their associated AC and DC systems. A conventional approach to filter these harmonics is to use passive filters on both AC and DC sides of the convertor.

High Voltage, Volume 11, Issue 4, Page 928-938, August 2026.ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

Space charge determination in HVDC power cable and its influence on electric field
, 2010 Considerable amount of transmission and distribution of electricity is carried out by power cable. At present, most high voltage direct current (HVDC) installation uses traditional (oil-impregnated paper insulation and oil-filled-types) cables which pose
