Aging Characteristics of the Insulation Layer of HVDC Cables and Effect of Space Charge Accumulation on Electric Field Distribution

IEEE transactions on dielectrics and electrical insulation
The aging of the insulation sample of high voltage direct current (HVDC) cables is one of the main reasons that aggravates space charge accumulation.

Space charge accumulation in undersea HVDC cables as function of heat exchange conditions at the boundaries – water-air interface

2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON), 2020
Transmission lines with undersea HVDC cables are an interesting technological solution for the supply of electrical energy to islands. The accumulation of space charge inside the dielectric layer of a HVDC cable is one of the most important element to ...

Innovative Electrodes for HVDC Submarine Cables

IEEE Transactions on Power Delivery, 2016
The number of HVDC submarine cable connections is increasing around the world. In these applications, electrodes design is paramount for technical and economic feasibility. Cathode's design is kept as simple as possible, if bidirectional operation is not required, since reduction reactions do not produce corrosion of the material.

Space charge in HVDC cable insulation

IEEE 1997 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2002
High voltage cables that are used for DC transmission are subjected to a range of operating conditions. The resulting distribution of the electric field inside the cable is highly dependent on, for instance loading of the cable and polarity reversals.

Advanced HVDC XLPE cable and accessories

9th IET International Conference on Advances in Power System Control, Operation and Management (APSCOM 2012), 2012
We have found that the issues in the DC properties of conventional cross linked polyethylene (XLPE) can be solved through the DC-XLPE insulating material. The DC-XLPE's major advantages against conventional XLPE are as follows: High volume: resistivity: Low space charge accumulation: High DC breakdown strength: Long DC life time The HVDC cable system ...

Effect of protrusions in HVDC cables

IEEE Transactions on Dielectrics and Electrical Insulation, 2012
This paper presents an analysis to determine the effect of the stress enhancement factor due to the presence of protrusions in the semiconductor shields of HVDC cables. The theoretical analysis of the electric field containing protrusions is based on a harmonic solution for the electric field for spherical and spheroidal protrusions.

World record HVDC submarine cables

IEEE Electrical Insulation Magazine, 1994
On Oct. 1, 1993 a new 350 kV/440 MW HVDC cable was commissioned between Norway and Denmark. This 127 km-long, Skagerrak 3 cable was manufactured bv Alcatel Kabel Norge. It was installed at a record maximum sea depth of 530 m. During the summer of 1994 a 250 km-long, 450 kV/600 MW HVDC cable will be installed across the Baltic Sea from Sweden to Germany.
