Abstract

The stochastic model of partial discharges (PDs) in chains of gas caverns in condensed dielectrics is improved. The equations for electric field potential are solved in a region filled by dielectric containing gas caverns. The opportunity of a "relay-race"propagation of PDs in a linear chain of gas caverns under constant and ramp voltage was shown in previous studies. This mechanism is possible if the interval between caverns is relatively small. In this case, the wave of PDs can travel along the chain. This paper is devoted to modelling "relay-race"waves in a zigzag chain of gas-filled caverns under AC voltage.
