Dielectric Modeling of Liquid Insulations

Roman Cimbala

Abstract


Abstract. Paper deals with theoretical background of dielectric modeling of liquid insulation materials. At present three methods exist and are
worldwide in use: the analysis of relaxation currents (PDC, Polarisation and Depolarisation Current), analysis of the dissipation factor tan δ over a
wide frequency range (FDS, Frequency Domain Spectroscopy) and analysis of the recovery voltage (RVM, Recovery Voltage Measurement). In
practice, different methods applied on the same It is well-known that different results for chosen properties ere caused only by modeling the
insulation system and the material samples for getting basic dielectric measurements.
