Temperature and humidity influence on insulation resistance of electric motors
 Fiala, Petr ; Vetiška, Vojtěch (referee) ; Ondrůšek, Čestmír (advisor)
The bachelor‘s thesis studies the effects of temperature and relative humidity on the insulation resistance of electric motors and their polarization index. The first chapter describes measuring principle of insulation resistance, measured objects, used measuring instruments and actual environmental conditions. The second chapter defines the basic requirements of insulation systems and there is especially solved evaluation of the measurement of individual parts of motors and calculation of polarization index. Third chapter discusses the influence of temperature and relative humidity on insulation resistance, there are formulated general preconditions and after using climate chamber there are presented measurement results on real motors in the industrial practice.
