The objective of this paper is to determine asynchronous discharge characteristics of two serial connected vacuum interrupters under lightning impulse voltage. Two commercial vacuum interrupters were used in the experiments. Two 12 kV commercial vacuum interrupter (VI) with the contact material of C...
