The main purpose of this study is to determine and evaluate the e ff ects of the conditions that may occur in real working conditions but out of the type tests. As for the disconnector model, one phase of a center-break disconnector was considered. In order to examine the e ff ects of composite voltages on high-voltage disconnectors, a model is de fi ned in the Comsol Multiphysics program. Di ff erent types of voltages such as operating voltage, 50 Hz test voltage, lightning impulse voltage, and composite voltage, were applied to the 170 kV disconnector model separately. After applying a composite voltage consisting of power frequency voltage and lightning impulse voltage to the disconnector, electric potential and electric fi eld distributions were obtained. It has been observed that the maximum electric potential and the maximum electric fi eld strength values on the disconnector are higher when composite voltage is applied than when non-composite voltage is applied to the disconnector. It is observed that the intensity of the electric fi eld lines increases near the contacts of the current-carrying arm and the main contacts of the disconnector.","PeriodicalId":36781,"journal":{"name":"Electrica","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140474873","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 iris con fi gurations and iris parameters have been minutely studied and e ff ective postulates have been provided for accurate design of fi lters with low IL throughout the transmission bandwidth. Basic structure is designed over a substrate with dielectric constant 3.2 and material thickness of 30 mils. The structures are then successfully modi fi ed into a band-pass fi lter with its pass band in Ku bands with minimal IL using waveguide iris method. The technique e ff ectively serves the purpose to achieve greater control over the IL and isolation. Maximum IL of 2 dB is reduced by 1.5 dB and close to 0.5 dB IL is obtained in the fi nal con fi guration using the tapering technique. Proposed techniques are supported with theoretical explanations. All designs are fabricated, and measured results are found to validate the concept produced in this paper. The study provides a direct solution to the SIW Iris fi lter design engineers considering all major parameters necessary foriI ndust rial/ scien ti fi c productions.","PeriodicalId":36781,"journal":{"name":"Electrica","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140478552","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}
