The ionic space charge in the micro-voids of water tree will produce a period vibration by AC voltage stimulating. Under superposition voltage, the vibration can impel the ion penetrating into the tiny crackle between micro-voids of water tree and lead to a change in the conductivity of water tree. With this the ultra-low frequency spatial current signal of the water tree would be emerged in detecting circuit. The polarization and depolarization of the polar end-group of the PE formed in water tree developing will also contribute to this special signal.

本文分析认为，水树枝中的离子型空间电荷在几种电压共同作用下会发生周期性振动，这种振动会促使水树枝中的导电离子在较低的叠加电压激励下进入连接水树枝微孔的微裂纹，微裂纹导通不仅导致水树枝的电导发生变化，而且在检测回路中会有水树枝老化超低频特征信号电流产生。
