Think of the ionosphere and the ground as the terminals on the battery and you put a wire between those twoterminals and current flows, and literally you get a spark.
把电离层和地面想象成电池的两极。 用一根导线连接这两极的话，电流就会流动，然后就会产生火花。

Using post fault voltages and currents from the twoterminals, a novel method for fault location based on transmission line's equivalent sequence networks is proposed in this paper.
利用输电线路两端的故障电压、电流量，提出了一种基于输电线路等效序网的故障测距方法。

Currently, group in China has twoterminals in operation, located respectively in Guangdong daya bay Economic and Technological Development zone and Nanjing Chemical Industrial Park.
