Abstract: 3D simulation of the initial stage of the development of gas discharge in a helium bubble in dielectric liquid between flat electrodes has been performed with the use of a diffusion-drift approximation. The values of the electric field in the bubble and on its surface were obtained before and after the electrons reached the bubble boundary. The electric field strength increased from 48 kV/cm to 79 kV/cm at the pole of the bubble closest to the anode. Data on discharge characteristics at the initial stage within the framework of the considered model are obtained: plasma concentration, distribution and evolution over time of concentrations of positive helium ions and el
