This paper describes multiple electric field control methods for foil coils in high-voltage coreless linear actuators and their sensitivity to misalignment. The investigated field control methods consist of resistive, refractive, capacitive and geometrical solutions for mitigating electric stress at edges and corners of foil coils. These field control methods are evaluated using 2-D boundary element and finite element methods. A comparison is presented between the field control methods and their ability to mitigate electric stress in coreless linear actuators. Furthermore, the sensitivity to misalignment of the field control methods is investigated.

“…The reason for such a conclusion is that the physical structure of the cable accessory is very complicated. Accordingly, electric field in the accessory is easy to be distorted, resulting in the enhancement of field at some certain points [1]. Therefore, from the viewpoint of safety, it is very important to investigate the interface discharge behavior within a cable joint or a cable terminal.…”

Abstract-Electric field distribution in cable joint can be enhanced because its structural complexity, this forms interface discharge between the main insulation of cable and the insulation of cable joint. Polypropylene (PP) has good electrical property and is suitable for being used as insulation material of power cable. On the other hand, silicone rubber (SiR) has been widely used as the insulation of cable joint. The interface between the PP and SiR becomes a weak point where an discharge phenomena may be introduced. In order to improve the electrical property of the interface, a corona discharge treatment has been employed in this research, by which the surface chemical and physical structures of PP can be modified. Obtained results showed that with the treatment of AC corona, the interface breakdown time was obviously extended. It is suggested that the interface breakdown strength can be enhanced through the corona discharge treatment method.

“…They have been an indispensable part of modern power system. It has been demonstrated in numerous articles that interface discharge along cable accessory tends to occur because of its strong distortion of electric field, which leads to the breakdown of interface and thereby inducing insulation failure to the cable system [1]. Consequently, with the purpose of operating the cable safely, it is of great necessity to investigate the interface discharge behavior within a cable joint or a cable terminal.…”

Abstract-Polypropylene has a great electrical property and may be used as primary insulating material in electrical power cable. In cable accessory, the field distribution is often distorted since the very complicated physical structure, which makes interface discharge between PP and cable joint insulation easy to happen. Polymer based nanocomposites has recently received a lot of attentions, which can offer a better insulation property than the neat polymer. In order to improve the electrical property of the PP/SiR interface, nano-sized MgO filler has been adding into PP matrix to form the socalled PP/MgO nanocomposites. The interface discharge behavior between the nanocomposites and the SiR have been studied. Obtained results showed that with the increase in the nano-particle content from 0 wt% to 5 wt%, the interface breakdown strength firstly increases but then decreases. A proper content of 3 wt% nano-sized MgO adding can improve the interface breakdown strength by a fact of 3.5. It is suggested that the interface breakdown strength can be enhanced through the adding of nano-sized MgO.
