Abstract :
This paper deals with free-conducting particle motion and particle-triggered breakdown mechanism in AC and DC electric fields between nonparallel plane electrodes. Particle motion is divided into several modes, and particle-triggered breakdown mechanisms are discussed for each motion mode theoretically and experimentally. The obtained results suggest that several types of particle-triggered breakdown can occur in gas insulated system
