my-uitm-ir.845442024-02-23T03:41:48Z Analysis of transient overvoltage in medium voltage distribution / Shahrifawaty Abdul Aziz 2011 Abdul Aziz, Shahrifawaty There was a recent incidence where a direct lightning strike on distribution network which can cause the overvoltage. This paper presents the analysis of transient overvoltage in medium voltage distribution. Transient overvoltage is one of the common power quality disturbances in electrical distribution result from the unavoidable effects of lightning strikes. The objective of this paper is to analyze the performance of shield wire and surge arrester when lightning strike on phase wire and distribution substation. This analysis is performed by varying the value of lightning current stroke at medium voltage distribution. PSCAD/EMTDC software program is used to carry out the modeling and simulation works. Shield wire and surge arrester are installed as a protection from lightning strike at distribution network. The result of the significant role of shield wire and surge arrester in protecting overhead distribution lines is analyzed. The line with shield wire can reduce the flashover in open ground and surge arrester is the protection equipment that use for a better protection at distribution. 2011 Thesis https://ir.uitm.edu.my/id/eprint/84544/ https://ir.uitm.edu.my/id/eprint/84544/1/84544.pdf text en public degree Universiti Teknologi MARA (UiTM) Faculty of Electrical Engineering Hamzah, Noraliza |
