对美国洛斯阿拉莫斯国家实验室卫星测量的地球同步轨道等离子体参数进行了统计分析。以典型通信卫星为例，对每一组等离子体参数进行了充电分析。太阳能电池阵列上的预期触发弧的数量是基于在轨道上预期具有严重反向电势梯度条件的充电持续时间来计算的。利用触发电弧数，提出了一个合适的静电放电接地试验持续时间，以测试对持续电弧现象的绝缘强度。
Plasma parameters of geosynchronous orbit measured by Los Alamos National Laboratory satellites are analyzed statistically. For each set of plasma parameters, charging analysis is carried out, taking a geostationary satellite representing a typical telecommunication satellite as an example. The number of expected trigger arcs on a solar array is calculated based on the charging duration with severe inverted potential gradient conditions expected in orbit. Using the number of trigger arcs, an appropriate duration of electrostatic discharge ground test is proposed to test the insulation strength against sustained arc phenomena.
