| Popis: | The voltage response measurement is a non-destructive method to diagnose the aging condition of insulation and is used extensively. The characteristics about the volume polarization and resistance can be obtained by analyzing the measured decay or return voltage of a charged dielectric, which is important for aging diagnosis. To eliminate the influence of the charges leaking along the sample surface on the voltage response analysis, we present an effective three electrode configuration with a potential guard electrode. The voltage decay results show that adopting electrodes with a potential guard electrode can effectively avoid charge leakage along the sample surface. |
