1. CFD-modeling of labyrinth weir flood discharge with ice cover
University essay from KTH/BetongbyggnadAbstract : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. READ MORE

4. Dielectric Response and Partial Discharge Characteristics of Stator Winding Insulation System with SiC Stress Grading
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The typical construction of a stator coil includes the use of end corona protection (ECP)coating, which is made of semi-conductive materials like silicon carbide (SiC). Thepurpose of ECP is to smooth the electric stress distribution near the slot exit, limitingthe electric field and partial discharge (PD) activity within the insulation system. READ MORE

5. Measurements of partial discharge in insulators
University essay fromAbstract : Causes and effects of partial discharges (PD) inside electrical high-voltage insulation was studied prior to taking measurements with a PDS100 spectralanalyser during excursions to a number of substations in the Swedish electrical grid.This to develop a working-method and manual for workers to use periodically whileon site to be able to identify components on which maintenance is needed.
