It shows in theory that the frequency domain sounding in near zone of the line current source is possible.

通过对计算结果的分析，在理论上说明了线源频率域近区测深的可行性。

Moreover, three-phase four-wire active filters can suppress zero line current, and solve symmetric problem of system effectively.

另外，三相四线制有源电力滤波器能有效地抑制零线电流，并能有效地解决系统的不对称问题。
