Discharge characteristics in a narrow gap between two insulators have been investigated for a needle-plane electrode configuration with a point backside electrode. The negative flashover voltage decreased when backside electrode became longer. Moreover, the flashover voltage with a backside electrode below the needle was lower than one without a backside electrode. These characteristics were more remarkable in a negative needle. In the case of a configuration with a backside electrode, corona generated from the needle has easily extended to the gap. On the other hand, for the case of configuration without backside electrode, the corona has hardly extended to the gap, and then by increasing applied voltage the corona has greatly developed in the gap. The corona extended until the place where a backside electrode exists. This difference on the corona extension should affect to the flashover characteristics in the present system.
