In this paper, an electrometer is used to test the electric potential distribution under the unfolded one layer film of one capacitor component, and the residual charges on the dielectric films are calculated by the inversion method of electric potential and charge.
In general, the charge distribution on the capacitor dielectric film is uneven and irregular, and the polarities of the residual charges can be positive or negative. Fig. 4.

When the residual charge densities are 0 and 10 −6 C/m 2, the forces on the interface are not much different. When the residual charge density is 10 −4 C/m 2, the force on the interface reaches the maximum and the value is 6.2 × 10 4 Pa. It can be clearly seen that the electric field forces on the dielectric films are not equal.
Fig. 2. The residual charge measurement experiment set-up. The potentials measured by the electrometer decrease with the increase of distance between the probe and the film. Therefore, the electrometer was calibrated according to the measuring distance before the experiment.
When the surface of the dielectric film contains residual charge, there are some distortions caused by the 50 Hz component in the waveform, and the electric field stress at 50 Hz (excitation frequency) increases gradually. So 50 Hz component in the tested results shows that there are residual charges on the surface of dielectric film.
