Characterization of traps in dielectrics is very important to properly describe their space charge behavior. An alternative technique to standard Isothermal Surface Potential Decay measurements is proposed in this paper. The proposed method allows for estimation of potentials both during the polarization phase and immediately after depolarization of surfaces, monitoring of fast surface potential transients as well as slower ones. Results from both evaluations and space charge depolarization measurements on samples of DER332 epoxy resin are in good agreement with each other, showing that there are two predominant traps at energies of 0.81 eV and 0.92 eV respectively and validating the proposed innovative procedure.

Abstract
Characterization of traps in dielectrics is very important to properly describe their space charge behavior. An alternative technique to standard Isothermal Surface Potential Decay measurements is proposed in this paper. The proposed method allows for estimation of potentials both during the polarization phase and immediately after depolarization of surfaces, monitoring of fast surface potential transients as well as slower ones. Results from both evaluations and space charge depolarization measurements on samples of DER332 epoxy resin are in good agreement with each other, showing that there are two predominant traps at energies of 0.81 eV and 0.92 eV respectively and validating the proposed innovative procedure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
