Influence of trimer water cluster in liquid materials on conduction phenomena by using nano-second pulse

The effect of trimer water cluster on conduction phenomena was investigated using three kinds of liquid dielectrics: di-octhyle-phthalate (DOP), including dimer; acctonitrile (ACT), including dimer and much trimer; and a mixture of ACT and DOP. It is shown that, when the concentration of DOP in the mixture increases, the amount of trimer decreases and the cluster becomes smaller. In the conduction test, it is evident that the conduction current is electron current. It is also shown that, as the amount of trimer decreases and the cluster becomes smaller, the electron current decreases. This conduction phenomena appears to be due to trimer bridges.<>
