Therefore, power companies are constantly seeking new ways to create more effective cable termination designs. In order to improve cable termination design, it is required to understand the nature of weak points at the cable end. Partial discharge measurement is a non-destructive measurement method, which can be used to access insulation quality. Therefore, this work investigates partial discharge severity of unterminated cable ends under various conditions to observe the strongest factor that degrades the insulation quality at the cable end. Factors which determine good cable termination design may also be attained from the measurement results of this work.","PeriodicalId":126366,"journal":{"name":"2014 IEEE International Conference on Power and Energy (PECon)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126266361","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 proposed scheme analyses the absolute values of three phase current signals over a half cycle to obtain detail coefficients. These detail coefficients of half a cycle are compared with those of previous half cycle to compute alienation coefficients which are further utilized to detect and classify the faults. The proposed technique was able to discriminate non-fault transients such as capacitance, inductance and load switching, from fault transients. The increase in the sensitivity of protection scheme, due to utilization of wavelet based detail decomposition, has been established by case studies.

However, flashover fault still occurs on this insulator type. Under certain conditions, partial discharges may occur on the insulator and lead to a complete flashover. The flashover can cause the breakdown and damage the whole power system. Therefore, this paper reports on the flashover voltage of 11kV composite insulator under different conditions. They are pollution methods, insulator surface condition, water content, operating orientations and the ambient temperature. It was found that the flashover voltage can be improved by using 0° operating orientation angle of the insulator, at lower temperature, dry condition, less insulator surface roughness and no pollution on the insulator. Therefore, a better understanding of flashover voltage under different pollution conditions may be attained from this work.","PeriodicalId":126366,"journal":{"name":"2014 IEEE International Conference on Power and Energy (PECon)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125972465","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}

In this paper, we present a system in which a wireless sensor network is used for continuous wirelessly monitoring contamination in high voltage insulators. The new system consists of different sensor nodes (e.g. humidity, temperature and dust) mounted on a dummy insulator that has to be placed close to high voltage substation or transmission line tower. The proposed approach is based on the Equivalent Salt Deposit Density (ESDD) severity method in order to check the pollution level on the insulator and to correlate with flashover voltage levels of the insulator string. In this approach, the photons measurement level (i.e. light intensity) is adopted as an indicator to the accumulated pollution level on the insulators. Extensive lab tests were carried out using different pollutants. ESDD measurements have been collected for all the pollution tests performed in the lab and a relationship between these values and the light intensity values has been established to correctly model the contamination level. Using, the established relationship between EESD and light intensity shall enable the power system control unit to accurately predict the flashover and accordingly schedule its crew to visit the site and clean these insulators.","PeriodicalId":126366,"journal":{"name":"2014 IEEE International Conference on Power and Energy (PECon)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115102922","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}
