1. 6. Shaft Current Protection

   Master-uppsats, KTH/Industriella informations- och styrsystem

   Sammanfattning : Shaft current protection in hydro and turbo generators is an important generatorprotection issue. Currents owing in the generator shaft might damagegenerator bearings which, in turn, could reduce operating time and cause largenancial losses. Therefore, it is important to prevent operation of the generatorunder conditions of high shaft currents. LÄS MER

3. 7. Measurement of internal current densities during a HiPIMS discharge with a Rogowski coil

   Magister-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Magnus Karlsson; [2011]
   Nyckelord :HiPIMS; HPPMS; plasma; electron transport; Rogowski coil;

   Sammanfattning : In this study, the current densities in three different directions (r, φ and z) have been measured above the target during a HiPIMS discharge by the use of a Rogowski coil. This was done to examine the key transport parameter Jφ/JD┴ = ωge TEFF throughout the whole measured area, which is a key parameter describing how electrons are transported across magnetic field lines.
