Thus, polymer nanocomposites become one of the main research areas for exploring the potential of insulating materials in terms of dielectric strength enhancement. This is due to many convincing results of nanocomposites capabilities reported by researchers. For this, this work explores the influence of Silicone Dioxide (SiO2) and Zirconium Oxide (ZrO2) on the dielectric strength of Cross-linked Polyethylene (XLPE). The mixture between the filler and the base polymer is one of the major factors for improving the characteristic of the nanocomposites. The unfilled XLPE and nano-filled (1wt%, 3wt%, 5wt% and 10wt%) XLPE are prepared from powder to pallets using extrusion and crosslinking processes. These methods have been used to prepare nanocomposite samples into thin layers of 1mm. The samples are tested under AC breakdown performance of unfilled and nano-filled XLPE according to ASTM D149 standard. The results observed an improvement of breakdown performance at the low usage of nanofillers. A comparison based on SiO2 and ZrO2 has shown different behaviours. Therefore, this study investigates the effect of these nanofillers on the performance of nanocomposites under both AC performance.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"375 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":"133093226","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}

The electric field distribution along an insulator string is not uniform when an AC voltage is applied on it. To prevent unwanted phenomena such as corona discharge or flashover from happening, the electric field near the energized end of the insulator string must be minimized. This can be done by installing a corona ring. It is important to obtain a suitable design of corona ring so that the electric field magnitudes can be reduced significantly. Therefore, the effect of the design of corona ring on the electric field distribution along a 10-unit porcelain insulator string was evaluated by using Finite Element Analysis (FEA) in this work. From the simulation results, it was found that the parameters of the corona ring such as the vertical height of the corona ring along the insulator string, the outer diameter of the corona ring, and the inner diameter of the corona ring tube have an impact on the electric field distribution surrounding the insulator string. At the end, a suitable design of corona ring is proposed, which gives the lowest electric field magnitude along the insulator string based on the results obtained. A suitable design of corona ring for the modelled 10-unit porcelain insulator string was found to be 350 mm outer diameter of the corona ring, 65 mm inner diameter of the corona ring tube and 300 mm vertical height of the corona ring along the insulator string.","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":"130703016","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}

Thermal and electrical stresses are the major cause of concerns for failures in a power transformer. These stresses are sustained by mineral oil (MO) which provides insulation as well as acts as a coolant in the transformer. MO is extensively used in power transformers for insulation purpose since decades. To overcome the thermal and electrical stresses it is important to enhance the insulation properties. This can be possible by suspension of Nano-sized particles in the oil i.e. nanofluids (NFs). NFs have changed the trend in terms of breakdown, moisture saturation capabilities, etc. The generation of leakage flux in the transformer is responsible for the voltage dip on the load side; hence its reduction is important to maintain good voltage regulation and efficiency. This flux also flows through the liquid dielectric of a power transformer. Thus, it is very much important to analyze the magnetic nature of the liquid dielectric and its impact on the leakage flux. To study this phenomenon, two types of oils are considered; MO and MO based NFs (MO-NFs) with Copper oxide (CuO) and Titanium oxide (TiO2) nanoparticles (NPs) dispersed in them. These oil samples are studied for their magnetic nature using vibrating sample magnetometer (VSM). The liquid insulation magnetization for both MO and MO-NFs is plotted with respect to magnetic field strength. The magnetic characteristics of MO based nanofluids (MO-NF) are discussed in the paper.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"18 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":"132840896","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}

Breakdown voltage test is performed to determine the breakdown strength of natural esters. In contrast, the stability of natural esters after the incorporation of natural fibre is determined by comparing the initial spectra of natural esters with the spectra of natural esters after several days. Natural ester used in this study is refined, bleached, deodorised palm oil (RBDPO). A natural fibre, rice husk, is used in the sieved form (63 microns) and is dispersed in palm oil. The breakdown voltage test is studied according to IEC 60156 using Megger OTS100AF oil tester. Then, the results are analysed by using Weibull statistical analysis. For the stability of samples, optical spectroscopy test is carried out by using UV-Vis spectrometer. The obtained spectra are compared with Day 1 and Day 8 of the samples to determine the filler dispersion stability in palm oil. As a result, the breakdown voltage of natural ester is improved when rice husk is added, which is expected due to the nature of rice husk as a moisture scavenger. The stability of natural esters decreased after a few days due to the agglomeration of fillers.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"22 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":"133719595","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}

Dissolved Gas Analysis (DGA) is the most commonly used method to identify the transformer fault in power system. However, the existing transformer fault identification methods based on DGA have a limitation because each method is only suitable for certain conditions. Thus, in this work, one of the artificial intelligence techniques, which is Support Vector Machine (SVM), was applied to determine the power transformer fault type based on DGA data. The accuracy of the SVM was tested with different ratio of training and testing data. Comparison of the results from SVM with artificial neural network (ANN) was done to validate the performance of the system. It was found that fault identification in power transformers based on DGA data using SVM yields higher accuracy than ANN. Therefore, SVM can be recommended for the application of power transformer fault type identification in practice.","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":"116987089","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}

Mineral oil has been used as an insulating liquid for over a hundred years. However, mineral oil is a non-biodegradable oil and has a serious impact on the environment and the non- renewable energy resources. Therefore, it is important to replace this oil with another alternative insulating liquid, and PFAE was introduced in the year 2006 in Japan. In addition, the ability of an insulating system also depends on the thickness of the monomolecular cellulose fiber on the kraft paper. Hence, it is necessary to determine the appropriate thickness of kraft paper for use as an insulator on the power transformer for this type of oil. This project presents paper-oil (PFAE) charging and discharging current characteristics. The study was carried out through the implementation of experiments in the laboratory. Polarization and Depolarization Current (PDC) test has been carried out to test the conductivity and response function of the insulating materials. It was found that the thickness of kraft paper affecting the capacitance value and the PDC measurement of the tested model. In both dry and wet conditions, the sample of two layers of kraft insulation paper shows the best insulation status as it has the lowest conductivity compared to the other samples. It can be concluded that it is necessary to determine the ideal thickness of insulating paper to ensure that the power transformer has the best insulation.","PeriodicalId":191189,"journal":{"name":"2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM)","volume":"23 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":"123564172","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}
