Space Charge Accumulation and Micro-Structure of Cross-linked Polyethylene
Japanese Journal of Applied Physics, 2004In this paper, laser induced pressure pulse (LIPP) method and electrostatic force microscopy (EFM) method are utilized to investigate the distribution of space charge in cross-linked polyethylene (XLPE), and the action on the groups of XLPE by the accumulative charge are investigated by infrared spectroscopy (IR) method.

Space charge accumulation and conductivity of crosslinking byproducts soaked LDPE
2010 Annual Report Conference on Electrical Insulation and Dielectic Phenomena, 2010The crosslinking byproducts have significant influences on the electrical performance of the Crosslinked Polyethylene (XLPE). In this paper, the effects of acetophenone, α-methylstyrene and cumyl alcohol on space charge formation and conductivity values have been investigated. The space charge measurement was conducted using Pulse Electroacoustic (PEA)

The effect of space charge accumulation in high voltage insulation systems
2017 18th International Scientific Conference on Electric Power Engineering (EPE), 2017Because of the financial savings and with respect for the environment, several efforts are made to replace AC voltage long distance transmission lines for DC voltage transmission lines. This may lead to increases of charging of insulation materials. The main aim of this paper is to describe the space charge accumulation in insulation material and its ...

Surface charge decay characteristics of epoxy spacer under space charge accumulation
Journal of Physics D: Applied PhysicsAbstract Under DC voltage, space charge inevitably accumulates within the spacer, thereby influencing the dissipation of surface charges. In this study, a charge measurement platform for epoxy resin spacers is constructed. The temporal variation of the surface charge distribution under space charges is compared. The results indicate that

The Influence of corona discharge on space charge accumulation in polyimide film
2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2013The space charge accumulation processes in polyimide film under corona discharge from spherical electrode are observed using improved open-electrode type PEA (pulsed electro-acoustic) measurement system. To reduce the electric power consumption, the efficient-energy motor is required to be developed.

Increase of refractive indices in liquid dielectrics by space charge accumulation
6th International Symposium on Electrets,(ISE 6) Proceedings., 2003Summary form only given, as follows. Distributions of refractive indices were measured with Mach-Zehnder and Schlieren techniques in liquid dielectrics where space-charge conduction took place with a parallel-plane-electrode configuration under direct voltage application.
