Description

The electric field strength was evaluated by using the intensity ratio of spectral bands of molecular nitrogen under streamer discharges in dry air at atmospheric pressure. The primary and secondary streamer discharges were observed in the needle-plane electrode by applying the positive impulse voltage. The reduced electric field strength of the primary streamer was 700 Td in this study and the value near the calculated one by simulation analysis.
