摘要
简介了二维暂态电场传感器。用该传感器进行长间隙放电测量的实验。定量测量了有流注和先导出现时，间隙中暂态电场的时空变化，定性分析了流注和先导的变化特性。测量结果与文献中的有关理论是相符的。
The sensor for the measurement of two -dimensional transient electricfield is introduced.With the sensor, the experiment of measurement of electric field isdesigned When the large air gap discharges is occurred.The temporal and spatialchange of the impulse electric field is measured quantitatively When a streamer or aleader occur in the gap.The characteristics of streamers and leaders are acquired qualnatively by the measurement of the transient electric field.The tested results are in agreement with the related theory in literatures.
