The effects of a modified surface morphology on space charge formation in low-density polyethylene (LDPE) were investigated with pulsed electro-acoustics. The change in morphology resulting from LDPE crystallization on atomically flat substrates was imaged by atomic force microscopy. An extensive lamellar morphology was observed, which contrasts with the crystal structure formed between PET films...
In order to understand the change rule and its mechanism for the space charge property of Magnesium oxide (MgO)/ LDPE nanocomposites after damp, the moisture absorption weight and space charge properties of wet LDPE and MgO/LDPE were studied. Experiments results show that moisture absorption has a strong influence on dielectric properties of MgO/LDPE nanocomposite. After nanocomposite had been exposed...
Summary form only given. Power devices and systems operating in partial vacuum are susceptible to partial discharges, corona, or volume discharge. In most cases, it is important to understand the characteristics of the discharge such as the space-charge distribution, the electron energy distribution, and collision processes in which the species are involved. Breakdown and spectroscopic studies of...
This paper presents an analysis of the distortion of the electric scalar potential around HVDC transmission lines. An iterative method has been developed to solve Poisson's equation for HVDC transmission line systems, accounting for the presence of space charges. The system can be in homopolar, bipolar or hybrid mode, and can include sky wires or non-corona conductors. The conductors in the bundles...
Corona discharge is a common phenomenon in high voltage transmission lines. The corona space charge arising from HVDC transmission lines is much more significant than that from HVAC lines due to the extended distribution of the space charge, which greatly influences the electric field strength on the ground and in space. A new iterative method has been developed to solve Poisson's equation for HVDC...
