Abstract :
The effect of dissolved gases (02, air and N2) and a widerange of concentration of organic additives (quinoline,toluene and naphthalene) on the electrohydrodynamic headdue to co-field motion in transformer oil and liquid paraffinhas been measured fof both uniform and nonuniform fieldsusing direct voltages. The effect of gap length on thehead was also examined. The results indicate that all thedissolved gases investigated as well as toluene and napthalenereduced the developed head, whereas quinoline increased thehead. With a highly nonuniform field the effect of 02 andtoluene was found to be strongly dependent on the polarityof the point electrode.
