“…A closer approach to nanoparticles reveals an overlap of interphase areas around nanoparticles as shown in Figure 1; the comprehensive analysis of the interphase thickness estimation has been found in [10]- [13]. The electrical characteristics of several industrial insulation materials and their effects on electrical applications have recently been explored theoretically and experimentally [14], [15]. Recent studies have been reported the effective dielectric constants of both interphase and inclusion areas of several nanocomposite models [6], [8], [15].…”

Partial discharge (PD) has a well-established relationship with the lifespan of power cables. This paper has been treated the polyvinyl chloride (PVC) with specified nanoparticles for enhancing dielectric degradation and reducing partial discharge current to extending lifespan of power cables. It has been succeeded to creation new polyvinyl chloride nanocomposites that have been synthesized experimentally via using solution-gel (SOL-GEL) technique and have high featured electric and dielectric properties. The validation of nanoparticles penetration inside polyvinyl chloride during synthesis process have been constructed and tested via scanning electron microscope (SEM) images. The partial discharge current mechanisms in polyvinyl chloride nanocomposites have also been simulated in this work by using MATLAB<sup>®</sup> software. This paper has explored the characterization of partial discharge current for variant void patterns (air, water, rubber impurity) in polyvinyl chloride nanocomposites insulations of power cables to clarify the benefit of filling different nanoparticles (Clay, MgO, ZnO, and BaTiO<sub>3</sub>) with varied patterns inside power cables dielectrics. A comparative study has been done for different partial discharges patterns to propose characterization of partial discharges using nanoparticles of appropriate types and concentrations.

Partial discharges occur the biggest failure problem in power cable insulation due to distortion of electrical stress. In this paper, it has been investigated on the effect of spherical nanoparticles of Barium titanate (BaTiO3) and Clay for enhancing electrostatic field distribution in single and three-core power cables. It has been applied new strategies of nanotechnology techniques for designing innovative polyvinyl chloride insulation materials by using nanocomposites and multi-nanocomposites. Moreover, it has been studied the electrostatic field distribution within power cable nanocomposites insulation in presence of air voids, water voids and cupper impurity voids. The electrostatic field distribution in power cable insulation has been calculated by finite element method (FEM). A comparative study has been investigated on the effect of nanocomposite insulation for enhancing electric field stress in power cables.

With the rapid development of communication technology and electric power industry, cables have been widely used. The demand for cables in various industries has risen sharply, so a variety of cables have appeared in the market. After a large number of cables are used, cable break failures occur frequently. In addition, most cables are installed in the special environment of high altitude or underground. Without professional testing equipment, line maintenance personnel can hardly find the fault location. Based on this, an efficient cable breakpoint location method is proposed, and the modulus maximum detection algorithm based on wavelet transform is studied to realize the cable breakpoint location. The wavelet threshold de-noising technology is used to remove the noise in the transmission signal and reflection signal collected by the system. By comparing the results of different wavelet decomposition, the optimal wavelet basis function is selected, and the modulus maximum sequence of the wavelet coefficients obtained after wavelet decomposition is calculated, then the time difference between the transmission pulse and the reflection pulse can be detected, and the location of the cable breakpoint can be further determined. The existing cables in the laboratory are tested for many times, and the actual test results are analyzed, which can meet the technical requirements of cable breakpoint detection.
