Electrical insulation of a vacuum interrupter (VI) is a composite system composed of vacuum, metal, and solid insulator. Detection of weak points in insulation is important for insulation design of VI. However, solid insulators of VI are mostly made

Vacuum circuit breakers (VCBs) are widely used in the medium voltage class. In VCBs, late breakdowns sometimes occur after the circuit current has been interrupted, and these late breakdowns are thought to be triggered by microparticles. In this pape

In vacuum discharge, we found that the discharge developing time depends only upon the discharge path length in the case of gap discharge, whereas it is in inverse proportion to the square of the discharge inception voltage in the case of surface fla

Vacuum circuit breakers are widely used in medium-voltage class. In vacuum circuit breakers, restrikes and non-sustained disruptive discharges sometimes occur after current interruptions. It is said that these late breakdowns are triggered by the mic

When using vacuum interrupters to switch capacitive current, the degree of insulation between the contacts tends to degrade as the broken welds are formed on the contact by making and opening operation. These broken welds locally enhance the electric
