The high ac voltage applied to the post insulator during experiment was 25kV corresponding to the highest voltage on a 20kV system. The level of insulator wetting has been referred to the average daily rainfall data in Indonesia. Three common rainfall values have been considered, namely 20mm, 50mm and 100mm, which are equivalent to the amount of watering level of 16ml/s, 30ml/s, and 60ml/s respectively. The results showed the significant effect of profile factor on the level of leakage current of post insulator both in clean dry and wet conditions.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"30 1","pages":"186-189"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73083383","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}

Controlling inside room temperature methods were used to analyze the energy costs for the ACs. The proposed study is to find out the impact of materials on inside room temperature and energy cost for ACs. A simulation study illustrates the effect of wall materials to define inside room temperature. In this research, an innovative material was built from mixed materials (such as: Styrofoam, soil and cement). The characteristics of material relates to heat transfer coefficient (Q), thermal conductivity (k) and output temperature (T2). Two kinds of steps were conducted to achieve this goal., Firstly, a simulation process was applied to define the temperature output of the innovative material. Secondly, energy costs were calculated based on the characteristics of this material under a simulation process. The results of research indicated that Q, k and T2 of an innovative wall material is effective in reducing energy cost for ACs.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"3 1","pages":"057-061"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74975761","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}

Even though ferroressonance is a transient phenomenon however the impact of the ferroresonance continue for a steady state that causes excess temperature and finaly damage the impacted apparatus . Therefore, this study concern to understand and identify ferroresonance phenomena and at the end to distinguish them from other disturbances such as overvoltage and harmonics. Ferroresonance initiation is carried out on a laboratory scale using a basic circuit of ferroresonance consisting of capacitors and transformers. Two kind of transformer core topologies, namely H type and M type, was used in the experiments. Moreover other disturbances such as harmonics was also simulated in laboratory. The ferroresonance and harmonic waveform then be processed using wavelet transformations and its cumulative energy was also determined. The results shows that for H type transformer the threshold value that distinguishes ferroresonance from other disturbances is about 9.24. On the other hand for M type transformer was about 7.97. Based on these values, the type of transformer core affect the energy level of ferroresonance. Moreover wavelet transformation could identify between ferroresonance and other disturbance under study very well, however further study should be done to investigate the effectivity of wavelet to discriminate all possible mode of ferroresonance.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"46 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76542721","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}

However, the applications of the conventional boost structure are gradually limited as the output power demand is continuously increasing.In this paper, an interleaved voltage-doubler boost PFC with coupled inductor is proposed. It has the advantages of high efficiency, high power factor and low harmonics. The proposed interleaved control strategy not only retains the advantages of traditional single-phase boost converters, but also reduces the volumes of energy storage inductor, output capacitor and EMI chopper at high output power. A coupled inductor is used to reduce the weight of the converter. The voltage doubled capacitors are alternately charged through a two-phase interleaving operation. Therefore, the voltage gain of the proposed converter is twice that of the conventional interleaved converter and it is suitable for high voltage applications.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"66 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90720098","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}

Drying is one of the methods to store fishery products longer. Conventional drying carries out with the medium of wind and sunlight. However, contamination of dust and other impurities cannot be avoided from conventional drying. Therefore, fish drying research will be carried out using a hybrid method with thermal collectors and solar panels to harvest solar energy which lead to increase efficiency and overcome the disadvantages of conventional fish drying. This tool model refers to the design of solar powered fish dryers with the development of additional thermal aisles and solar panels. The design of this study uses solar energy that is converted to heat through thermal collectors and cabinet spaces that resemble the greenhouse effect. Photons in solar energy are converted into electricity and become mechanical energy that will move the blower, that converted by photovoltaic. Air enters from the blowers to the thermal tunnel whose base is made of black plate as a thermal collector and the envelope is made of glass. Then hot air is brought to the cabinet drying chamber containing fish. The fish receives heat from the thermal collector and the cabinet system which also receives heat from the mirror installed on all three sides of the cabinet. Hot air containing moisture will come out on the cabinet's top shelf. The performance of dryers is measured by the value of efficiency and the quality of the fish. Based on experimental study, the efficiency of solar dryer is 43.15% and the bacteria test is 45 x 107 CFU/ml.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"88 1","pages":"156-162"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79384397","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 description is provided of how the method is implemented with a computer program via an example of a real substation. Effective interception of lightning relies not only on the method but also the hardware used.
