The displacement current from ramped voltage application to dielectric liquids

During ramped voltage application to dielectric liquids the displacement current has been measured and displays two kinds of anomalous behavior. First of all it may be positive or negative according to the type of fluid and it reverses sign at high field strength in transformer oil. Secondly, the displacement current is proportional to a simple power of the applied voltage. This property is shown to be related to the parameters governing the propagation of a Sine-Gordon soliton launched into the liquid by electron injection at the cathode. The first anomaly moreover is believed to be due to a displacement current component due to the annihilation of homocharge or heterocharge polar layers by electron injection at the cathode
