Structural characterization of LLDPE/MgO insulation composites in terms of space charge accumulation in an HVDC field

Popis výsledku v původním jazyce

This study addresses the critical role of insulation materials in high-voltage direct current (HVDC) transmission systems, emphasizing the challenges associated with space charge accumulation and slow polarization effects. The primary objective of this study is to investigate the utilization of linear low-density polyethylene (LLDPE) in High Voltage Direct Current (HVDC) applications, with a focus on enhancing its performance through the incorporation of magnesium oxide (MgO) nanoparticles. The research employs various techniques, including X-ray diffraction, nuclear magnetic resonance, broadband dielectric spectroscopy, conductivity measurements and pulse electroacoustic measurements, to analyse the internal structure, crystallinity, and space charge dynamics of LLDPE/MgO nanocomposites. The results demonstrate that controlled MgO incorporation optimizes the internal electric field, improving the electrical properties without significantly altering the charge decay rate. The multidimensional approach of the study provides valuable insights into tailored modification of insulation materials for enhanced HVDC transmission performance, considering both electrical and structural aspects.
