Among the proposals found to detect the contribution portions coming from the supplier and the customer, it is noteworthy that, in general, the methodologies based on principles use the frequency domain harmonized with the superposition of effects. Despite the simplicity of this procedure, it is emphasized that it relies on measuring information and on the previous knowledge of the equivalent harmonic impedances of the utility and customer, whose information are of difficult access. In this context, this paper is focused on a feasibility proposition to solve the above mentioned difficulties in obtaining the percentage of responsibility between the parties.","PeriodicalId":369941,"journal":{"name":"11th International Conference on Electrical Power Quality and Utilisation","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115498435","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 main advantage of the algorithm proposed is that it can handle applications with unparallel arrangements between OHL and pipelines and therefore the induced potential and current values are more accurately computed than the traditional software packages. For this purpose, an original full 3D electromagnetic field model was developed. The computational module is based on a coupled Finite elements (FEM) — Boundary elements (BEM) numerical analysis technique that is detailed in the first part of the paper. The computation accuracy of the numerical algorithm developed was tested considering simple cases and comparing the numerical results with those obtained using a known software package based on the Transmission Lines Method (TLM). In the second part of the paper an application in the case of a OHL working on normal and fault conditions is outlined. The importance of the magnitude and direction of the currents flowing through the OHL on the induced potentials distribution along the victim pipeline is outlined. The final conclusions end the paper.","PeriodicalId":369941,"journal":{"name":"11th International Conference on Electrical Power Quality and Utilisation","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124897088","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}
