Current pulses caused by microparticle motion in vacuum and gas high- voltage insulation systems

The paper presents a computer program allowing for determining a time pattern of the current flowing through a vacuum or gas high-voltage insulation system, in result of the motion of a microparticle (being a small charged metallic particle) occurring in the inter-electrode gap. Moreover, the program calculates the velocity of the microparticle impact against the opposite electrode surface and the critical velocity of inelastic collision with the surface.
