Charge Distribution and Electroluminescence in Xlpe under Dc Field
The intent of this paper is to cross-correlate the information obtained by space charge distribution analysis and electroluminescence (EL) detection in cross-linked polyethylene samples submitted to DC fields, with the objective to make a link between space charge phenomena and energy release as revealed by detection of visible photons. Space charge measurements carried out at different field l...
متن کاملElectrical Characterization of Polymeric DC Mini-Cables by means of Space Charge & Conduction Current Measurements
ii Τὸ εὖ γίνεσθαι μὲν παρὰ μικρόν, οὐ μὴν μικρὸν εἶναι. Abstract The world's first commercial High Voltage Direct Current (HVDC) transmission link was built in 1954 between the Swedish mainland and the island of Gotland. At that time, it was proved that HVDC transmission is technically feasible. Since then, HVDC cable systems have been used worldwide in electrical energy transportation. Most HV...
متن کاملThe Influence of Material Modification and Residues on Space Charge Accumulation in XLPE for DC Cable Application
Effects of cross-linking by-products (residues) of polyethylene on space charge accumulation and decay are investigated in the paper using the pulsed electro-acoustic technique. Space charge profiles have shown a great variation both in the charge initiation over the voltage ramping up process and later on long term stressing and decay (volts off) among the samples subjected to different condit...

متن کاملHigh Frequency Characteristics of Medium Voltage XLPE Power Cables
The response of a cable can be used to analyze the variation of the material characteristics along its length. For diagnosis of possible ageing, it is necessary to know how cable design, material properties and cable insulation ageing affects the wave propagation. A cable model has therefore been worked out based upon the high frequency properties of the cable insulation and conductor systems. ...
