The electric field surrounding the MOA can be made uniform by installing a grading ring. It is important to have a proper way to design a grading ring with low electric field of the design. In this project, a model of 150 kV MOA was developed in COMSOL Multiphysics software. The grading ring dimensions were varied to study their effects on the electric field surrounding MOA. It was found that the grading ring dimensions strongly influence the electric field magnitude surrounding the arrester. Gravitational search algorithm (GSA) were used to obtain the optimum design of the grading ring for the MOA model. Comparison of the results between GSA and other optimization methods shows that GSA is the most suitable method to obtain an optimum design of the grading ring for MOA compared to genetic algorithm (GA), particle swarm optimization (PSO) and simulated annealing (SA). This is due to it yields the lowest electric field magnitude and has the fastest convergence.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123115168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, this research is performed in order to analyze more on the effect of SiR formulation with different filler content, their curing characteristic and their effect upon sample performances electrically. Firstly, SiR will be formulated with three different concentration of Alumina Trihydrate (ATH) of 10wt%, 20wt% and 30wt% together with Dicumyl peroxide (DCP) as the curing agent. The cure characteristic of the SiR with all three different concentrations were tested using rheometer in accordance to ASTM D5289. The prepared SiR materials were then tested according to the standard of BSEN 60587 Inclined Plane Tracking (IPT) test in order to analyze their performances electrically via leakage current (LC) values. It was found that increase in filler loadings were followed by increase in crosslinking density (MH) and decrease in scorch time (TS2). The cure time increases with increase in filler loadings. The increase in filler loading up to 30wt% together with crosslinking density (MH) have contributed towards a SiR material with great electrical properties. The highest ATH loadings of 30wt% displayed the highest crosslinking density, lowest scorch time, highest cure time and lowest LC value of 9.7 mA. In overall, a combination of proper ATH filler loading contributes to a high crosslinking density and higher resistance of sample against tracking and erosion and hence a lower LC value.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124837368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A glow discharge is a homogeneous and effective mechanism of cold plasma for industrial applications due to the continuous and stable discharge process compared to the filamentary discharge. Meanwhile, the development of glow discharge plasma operated under atmospheric pressure condition is indispensable to overcome the weaknesses of filamentary discharge plasma, such as the nonuniform and discontinuous discharge process. The discharge mechanism is essentially dependent upon the input parameters of the plasma system, such as the amplitude of the voltage supply, the operating frequency, and the flow rate of the background gas. In this paper, the effects of voltage supply on plasma discharge characteristics produced from the plasma jet reactor with the high-voltage electrode are discussed. The value of voltage supply is tuned to be suitable with the discharge gap, frequency supply, and background gas flow rate in producing the homogeneous glow plasma discharge. The characteristics of the glow plasma discharge produced are analyzed based on the pattern of the charge-voltage Lissajous figure and time-domain discharge current techniques. Results show that the most efficient and uniform plasma is disclosed by the configuration of input parameters such as 0.5 kV of supply voltage, 20 kHz of operating frequency, and 0.8 L/min of purified helium gas flow rate. The parallelogram-like Lissajous figure obtained indicating the homogeneous plasma discharge with a constant value of discharge capacitance.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126284997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Potential incidence may happen in the power cable, which is space charge phenomena, increase in the electrical field and can lead to a breakdown in the insulator. More precisely depends on fillers' effect on electrical field distribution with different relative permittivity and size of the filler’s particle in the insulation cable. Furthermore, this review implicates ample discussion regarding the impact of two materials considered as a filler material with nanometer size (100nm = 0.0001mm) and micrometer size (100µm = 0.1mm) which is zinc oxide (ZnO), borosilicate (SiO2). The study goal is to determine the impact of filler size, type and distribution of particles into the polymer matrix on the electrical properties such as relative permittivity, electrical breakdown and the average of the electrical field added to the structure for Nano and Micro size with fillers and without fillers are analyzed. Finally, it was concluded that the size of fillers gives a huge effect on the reduction of electric field compared to the different types of material with different relative permittivity.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126161878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper addresses the effect of UV aging of ethylene-vinyl acetate copolymer (EVA) with three different nano zinc oxide (n-ZnO) contents (0.05, 0.1, and 0.15 wt%) was performed in a xenon arc source chamber. Pure EVA, 0.05, 0.1, and 0.15 wt% of EVA/n-ZnO nano composites were prepared by solvent casting method using toluene as solvent. The prepared samples were exposed to UV light generated 0.51 W/m2 irradiance from a xenon lamp at 340 nm wavelength for 1000 hours. The effect of UV ageing on thermal, mechanical and electrical properties of EVA nanocomposite encapsulant has been investigated. Thermal conductivity was studied at room temperature (25°C) and at elevated temperature of 50 °C for before and after ageing samples. Tensile strength and elongation were conducted to check the mechanical properties after ageing. Water contact angle measurement was conducted to check the wettability of the encapsulants before and after ageing. It was observed that 0.1 wt% of EVA/n-ZnO nano composite retains better physical, mechanical and electrical properties.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127288139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
