A STUDY OF THE EFFECT OF SPACE CHARGE ON THE DIELECTRIC AND CONDUCTIVE PROPERTIES OF AN INSULATING FLUID

Abstract

The effect of the space charge on the properties of an insulating fluid were studied under flowing and static conditions by comparison of the current and space potential distribution for various voltages applied to parallel plates in the fluid. The static test showed a building up of space charge which (1) reduced the current over the first 15 to 30 minutes to a final value of 1/2 to 1/5 of the initial current, (2) caused the potential distribution to be non-linear, and (3) increased the bound charge on the plates. The test with just measurable flow showed the space charge and its effects were virtually eliminated. The experimental data also permitted estimates of the amount of space charge and the charge mobility.
