Partial Discharge Measurements in HV Rotating Machines in Dependence on Pressure of Coolant
Keywords:partial discharges, stator insulation, high voltage rotating machine, phase resolved partial discharge analysis
AbstractThe influence of the pressure of the coolant used in high voltage rotating machines on partial discharges occurring in stator insulation is discussed in this paper. The first part deals with a theoretical analysis of the topic. The second part deals with the results obtained on a real generator in industrial conditions. Finally, theoretical assumptions and obtained results are compared.
