摘要：

This paper presents both experimental investigations and computer simulations on the phenomenon of multiple prestrikes and associated prestriking overvoltages during energizing a capacitive load (capacitor bank or unloaded cable) by a vacuum circuit breaker. It has been found that the prestriking over-voltage is associated with multiple prestrikes, and the circuit parameters or arrangements play important roles on the severity of the prestriking overvoltages. A simple computer simulation program is established and verified with the experimental results. Further simulations of several probable practical cases are also provided. Normally overvoltages will not exceed 3 PU, but higher values are possible in special cases due to resonances in cable-line-cable networks.
