Fast Time Resolved Measurement and Simulation of Corona
As part of an overall effort to investigate partial discharge initiated deterioration of polymer dielectrics, partial discharge measurement and simulation have been explored. Fast time resolved measurements of corona in air have been made using electrodes and a passive component geometry designed for high resolution time measurements. The cathode employs a split configuration for use as a measuring electrode and coupling capacitor. A simple model has also been developed for the experimental system. The simulation uses swarm parameters and continuity equations coupled with electric field calculations to simulate the corona pulse. Both experimental results and simulations are reported and compared.
