Limitation of the electric field effects in a cylindrical tank by a system of grounding rods

The results of calculation of the 3D electrostatic field in a cylindrical tank provided with a system of vertical grounding rods are presented. The field intensities of the original tank without the grounding rods are very large, which may cause a spark discharge, even at a relatively small space‐charge density. The presented results involving the grounding rod system can be used to eliminate or reduce fire and/or explosion hazards.
