چکیده
In this paper the PD frequency dependence of a cylindrical cavity in a delaminated insulation is simulated using a field model. It is shown how the statistical time lag influences the PD frequency dependence. The technique of Variable Frequency Phase Resolved Partial Discharge Analysis (VFPRPDA) is applied to a test object and measurement data is compared with the results of the simulations.

Partial discharges in cylindrical cavities at variable frequency of the applied voltage
Measurements of partial discharges are commonly used to diagnose the insulation system in high voltage components. Traditionally a single fixed frequency of the applied voltage is used for such measurements as in the Phase Resolved Partial Discharge Analysis (PRPDA) technique. With the Variable Frequency Phase Resolved Partial Discharge Analysis (VF-PRPDA) technique the frequency of the applied...
متن کاملModeling of a discharging cavity in a dielectric material exposed to high electric fields
Partial discharges are localized electric discharges that do not bridge the electrodes. For high voltage components measurements of partial discharges are commonly used to diagnose the condition of the insulation system. Traditionally partial discharges are measured at a single frequency of the applied voltage. However the rather newly developed technique of Variable Frequency Phase Resolved Pa...
