This model incorporates a lumped series voltage source at the junction between the descending leader and an upward connecting leader launched from the top of the strike object. We have derived expressions for current along the strike object and along the lightning channel (both above and below the leader junction point), as a function of the lightning short-circuit current, and also for other special cases such as lightning strikes to flat ground with or without an electrically long upward connecting leader.

The damage mechanism is that a very short high level pulse may separate, due to the different modal velocities, into several lower level pulses at the location of the protection device, thus not triggering the protection, and then re-construct back into a higher level pulse further down the line, at the location of the vulnerable equipment. First, the essence of modal distortions is presented. Next, decomposition and restoration of a pulse in a structure consisting of two sections of multiconductor transmission lines are described. At last, the application of this phenomenon to power cables is shown","PeriodicalId":130489,"journal":{"name":"2006 17th International Zurich Symposium on Electromagnetic Compatibility","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122061245","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 WDCN acts as a bi-directional data communication link between the RAU & the control platform. It is based on Bluetooth technology and has a point-to-multipoint topology.
