Experiments and simulations of 4 MV coax-to-triplate multi-channel water self-breaking switch

A 4 MV coax-to-triplate multi-channel water dielectric self-breaking switch designed for oil and water section of PTS，the high power pulse device and primary test stand，is investigated on the prototype module of PTS. The switch contains three linear array self-breaking gaps and supporting hardware. The equivalent electric circuits of the prototype module of PTS and the switch are modeled based on the configurations of compositive parts. The results of experiments and simulations are compared at 2.9 MV and 3.3 MV break voltage of the switch. It is indicated that the simulative results agree with that of experiments well. It is important that the parameters of the equivalent electric circuits of the prototype module of PTS and the switch are selected reasonably. The Parameters approach to
