1. Fault location in resonant earthed medium voltage distribution systems
Sammanfattning : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.

2. Active and passive seismic methods for investigating the glacially-triggered Burträsk fault
Sammanfattning : Glacially-triggered faults are of high scientific interest since their formation was likely accompanied by major earthquakes and they are still a centre of seismicity in northern Fennoscandia, today. Imaging their deeper structure mainly relies on reflection seismics since the method generally has the best resolving power at depth of all geophysical methods. LÄS MER
3. Voltage Sags: Single event characterisation, system performance and source location
Sammanfattning : This thesis deals with one of the most important disturbances that affect the quality of the electrical supply. Voltage sags cause industrial processes malfunction, producing an enormous economical impact. A voltage sag is defined as a short duration reduction of the rms voltage. LÄS MER

Sammanfattning : .... LÄS MER
5. Managing Software Quality through Empirical Analysis of Fault Detection
Sammanfattning : Software often constitutes a large share of today's products. To deliver a product with the level of software quality expected by the customer, software development organizations need to manage quality achievement and assessment. In practice, quality is often referred to as the lack of bugs. LÄS MER
