Surface flashover switch have been investigated as a low inductance,low pulsed rate and low jitter command triggered switch.

This paper summarizes the relevant research of surface flashover switch.

Research and development of the surface flashover of ceramic insulators used in vacuum devices;

Surface flashover characteristics of polyethylene film under ns impulse voltage in vacuum;

Synchronization in laser-triggered surface flashover experiment;

But in engineering practice, due to the usage of oil-immersedsolid dielectric as equipment insulation supports, surface flashover across the oil-solidinterface happens easily and becomes the weakness factor of insulation.

The different glass-phase contents on surface of samples treated by hydrofluoric(HF) solutions of diverse concentrations affect their flashover characteristics in vacuum.

Based on the nanosecond(10 ns/30 ns) pulsed power vacuum experimental facility with Marx generator and single coaxial pulse-forming line,the vacuum surface flashover characteristics of the micro-stacked insulators were tested.

Preliminary experiment of vacuum surface flashover in nanosecond pulse voltage was done and micro-stacked insulator exhibited favorable vacuum surface flashover performance with flashover field strength of near 180 kV/cm.

There is no flashover occurred when the elec,tric field is less than 3kV/cm at the triple point(junction of a lucite wall with metallic wall anda vacuum).
