Outdoor insulators get contaminated easily due to various kinds of pollutants. Leakage current flows even when surface is dry though magnitude is very low but this leakage current gets strengthened due to increase in humidity, light rain, fog, mist etc. It ultimately leads towards flashover which is highly undesirable. Therefore, condition monitoring of power system insulators is very much necessary. Leakage current monitoring is one of the prime techniques for insulator monitoring. Leakage current consists of both volume current and surface current. Only surface current is affected by external causes like contamination and humidity. Therefore, surface current is a more accurate indicator for condition monitoring. Using harmonic analysis method surface current is extracted from total leakage current. Phase angle analysis at different humidity conditions has been carried out for both total leakage current and surface current. From above mentioned analysis, it may be observed that a significant difference in phase angle may be obtained when only surface current is considered instead of total leakage current. Therefore, this paper gives rise to the possibility of using only surface leakage current for more accurate condition monitoring of insulator.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130516068","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 petroleum product are going to be finished within next few decades, as well as emits greenhouse gases and air pollutant which are responsible for global warming. Efficiency of petroleum based automobiles is also low. The issues of the conventional automobiles can be overcome by replacing it with electric vehicle. An electric vehicle uses fuel cell as primary source of energy. For this application there is requirement of high power dc-dc boost converter, which step-up load voltage as per as vehicle requirements. Switching frequency of conventional boost converter is limited which results reduction in voltage profile of dc bus, so for eliminating problem of switching frequency components of two boost converters are combined using a single switch, known as quadratic boost converter. This paper introduces a sliding mode controller based quadratic dc-dc boost converter for fuel cell system. The stability of the proposed controller is determine by Routh-Hurwitz and robust loop shaping criteria which decides the range of Kp and Ki in which the close loop system always operate in stable region.

In this paper we try to explain two things one is PD test of insulating materials with higher applied voltage frequency and the other one is partial discharge model to explain the PD characteristics. For the first one, we use an IEC(b) electrode system known as a simple standard model electrode system to measure PD life time. PET (Polyethylene terephthalate) sheets with thickness of 100 micrometer are used under sine wave applied voltage with frequency range of 50 Hz to 10 kHz. We compared several PD characteristics at different applied voltage frequencies and we found that important PD characteristics such as the maximum apparent discharge magnitude is almost independent of the applied voltage frequency within the experimental conditions. This implies that PET film can be tested at higher frequency than power frequency to reduce the test time. The other one is the establishing a PD model to explain the PD characteristics based on the integral equation method and partly succeeded to explain the PD characteristics obtained by IEC(b) electrode system.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130311472","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}

Several additives and filler materials like BaN, ATH, ZnO etc were used in the recent past to improve the hydrophobic properties of silicone rubber insulators and thereby improving its resistance to tracking and erosion. In this paper the effect of pollution on composite insulators has been studied using the Inclined Plane Tracking and Erosion Test as per IEC 60587, while superimposing UV radiations. Pollutants used are fly ash, soot, bagasse ash and cement, to mimic the surroundings found commonly near coal mines and power generating stations. IEC 60587 however does not refer to the effects of UV radiations while performing the Inclined Plane Tracking and Erosion Test. In this study however, UV radiations have been superimposed on the specimen to study the effects of the same. During the course of study it was observed that the presence of UV radiations in fact reduced the erosion on polluted composite insulation specimen, while the tracking was found to increase. SEM and XRD analysis was also performed after the completion of test.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"387 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131788711","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 close proximity operation or hybrid operation of HVAC and HVDC transmission lines are also advantageous where availability of right of way is a main concern for transmission corridors. But with advent of this corridors, there associated effects has also became a major area for research work. The paper focuses on calculation of hybrid electric field in parallel erection of HVAC and HVDC transmission lines, which is often called as close proximity operation. Computation of hybrid electric field for this kind of lines is necessary so as to meet up the criteria's of engineering design and environmental protection issues. In this work, COMSOL Multiphysics has been used for the computation of the hybrid electric field distribution of HVAC and HVDC transmission lines under close proximity operation. For validation of the results, comparison has been made with the existing analytical methods as obtained from an extensive literature survey. The study has been further extended to obtain the distribution of electric field of hybrid transmission corridor at different levels from ground.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132095529","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}
