1. On reliability and maintenance modelling of ageing equipment in electric power systems
Sammanfattning : Maintenance optimisation is essential to achieve cost-efficiency, availability and reliability of supply in electric power systems. The process of maintenance optimisation requires information about the costs of preventive and corrective maintenance, as well as the costs of failures borne by both electricity suppliers and customers.

2. On reliability modelling of ageing equipment in electric power systems with regard to the effect of maintenance
Sammanfattning : Power system maintenance optimisation involves obtaining the minimum total costs, including preventive and corrective maintenance costs and the cost of failures for both supplier and customer. To calculate the cost of failure, information is needed about the equipment reliability characteristics. LÄS MER
3. Condition measuring and lifetime modelling of disconnectors, circuit breakers and other electrical power transmission equipment
Sammanfattning : 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. LÄS MER
4. Condition measuring and lifetime modelling of electrical power transmission equipment
Sammanfattning : The electric grid is important in modern society, so the outages should be few. The transmission grid should have a real high availability, since it transports electrical energy across the country. Then, it is difficult to plan outages for maintenance and installation. LÄS MER
