MATHEMATICAL MODEL OF TEMPERATURE DEPENDENCES OF THE DIELECTRIC CHARACTERISCTICS OF INSULATION SYSTEMS
Pavol Sandrik · 2001
The contribution treats a model of the temperature dependences of dielectric quantities needed for evaluating the diagnostic measurements on the insulating systems of rotating electric machines. The model is based on experimentally determined dependences. The choice of the model is based on the coecient of determination tested for statistical signicance. The outcome is a mathematical model, which can be used to process the results of diagnostic measurements. K e y w o r d s: dielectric properties of insulation system, temperature conditions, conversion to a reference value, insulation resistance, dielectric losses, permittivity, partial discharges, electrical strength, mathematical model.
