    Author : Peter Axelberg; Högskolan i Borås.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power transmission and distribution; digital signal processing; power quality monitoring; light flicker; power system disturbance; support vector machines; Medicinteknik; voltage dips; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; Electrical engineering; voltagedips; Support Vector Machines;

    Abstract : Developments in measurement technology, communication and data storage have resulted in measurement systems that produce large amount of data. Together with the long existing need for characterizing the performance of the power system this has resulted in demand for automatic and efficient information-extraction methods. READ MORE

  2. 2. Condition measuring and lifetime modelling of disconnectors, circuit breakers and other electrical power transmission equipment

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Per Westerlund; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reliability; maintenance; condition monitoring; disconnector; circuit breaker; Weibull distribution; prediction; risk analysis; decision making; beta distribution; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The supply of electricity is important in modern society, so the outages of the electric grid should be few and short, especially for the transmission grid. A summary of the history of the Swedish electrical system is presented. The objective is to be able to plan the maintenance better by following the condition of the equipment. READ MORE

  3. 3. Assessment of Interruption Costs in Electric Power Systems using the Weibull-Markov Mode
