1. Monitoring of Partial Discharges on Cable Terminations : An experimental approach to evaluate non-conventional online PD measurement techniques
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The transmission of electric power over long distances has historically posed challenges. However, the advent of high-voltage engineering has not only addressed distance barriers and power losses in electricity transmission and distribution, but it has also significantly improved the efficiency and transmission capacity of power grids.

2. Unsupervised Detection of Interictal Epileptiform Discharges in Routine Scalp EEG : Machine Learning Assisted Epilepsy Diagnosis
University essay from Uppsala universitet/Avdelningen Vi3Abstract : Epilepsy affects more than 50 million people and is one of the most prevalent neurological disorders and has a high impact on the quality of life of those suffering from it. However, 70% of epilepsy patients can live seizure free with proper diagnosis and treatment. Patients are evaluated using scalp EEG recordings which is cheap and non-invasive. READ MORE

3. Predicting Top-Oil-Temperature in Power Transformers with Light Gradient Boosting Machine
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Online monitoring of mineral-oil-immersed transformer variables provide capabilities such as failure avoidance, optimization of load capacity and maintenance as well as extending the remaining life expectancy. A central role is played by the Top-Oil-Temperature which in its own is an indicator of harmful events or transformer states. READ MORE
