Failure analysis performed by Cable Technology Laboratories noted a low ac breakdown strength and suggested a high insulation moisture content as a likely reason. Duke Power opted to treat the remaining (un-failed) cables using CableCUREreg life-extension, fluid injection technology. The treated cables remained in service for an additional 10 years after injection. Ultimately a termination failure led to the decision to remove them from service. This allowed an unprecedented opportunity to evaluate the responsiveness of solid dielectric, transmission cables to fluid treatment. Until now most of the 60,000,000 feet of injected cable has been in the distribution class of cables. The results of that evaluation, published in this paper, demonstrate treatment effectiveness on par with results obtained on distribution class cables","PeriodicalId":123024,"journal":{"name":"2005/2006 IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115721314","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}

It is a set of functions and capabilities that enables services for utility customers and also enables advanced applications that benefit the electrical system operation. Examples of portal applications include AMR, demand response, real time pricing, theft detection, remote disconnect, energy management, DER interface and control, and outage detection. Technologies for major aspects of the consumer portal, communications, security, and networking are available. The wake of failed portal pilot projects left by the utility industry demonstrates the need for a standardized, open architecture and gateway to allow technology providers to develop equipment and applications that meet the evolving needs of utilities.

The method uses synchronized voltage and current measurements from both terminals. Using positive sequence components of the pre-fault and fault waveforms, positive sequence source impedances are estimated. Using these source impedances and the line data, positive sequence bus impedance matrix (Zbus) is formed. Using the properties of Zbus, an iterative algorithm is proposed to locate the fault. This algorithm is applied to the data obtained from the EMTP simulation of two transmission lines. The simulation results show that though the method gives fairly accurate results for both medium and long transmission lines, its performance is better for medium and short lines","PeriodicalId":123024,"journal":{"name":"2005/2006 IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115997149","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}

Recently, the frequency environment of power systems has been made more complicated and the magnitude of second harmonic in inrush current has been decreased because of the improvement of cast steel. Therefore, traditional approaches will likely mal-operate in the case of magnetizing inrush with low second component and internal faults with high second harmonic. The proposed scheme enhances the inrush detection sensitivity of conventional techniques by using a fuzzy-neuro approach.
