Having the chassis grounded, as most equipment does, would seem to pose a challenge to the electrostatic model here, since excess charge should continue to spread out as long as there is a conductive path to a more neutral body, such as earth. However, all real-world ground connections have resistance and inductance which impede the flow of negative charge from the ground into the circuit. So, perhaps the effect we see is a dynamic one, wherein the BGT supplies negative charge to the chassis in the brief moments where the attached circuit draws sudden pulses and the ground is unable to instantaneously provide the needed charge due to its inherent impedance. There would then be a momentary depletion of negative charge in the ground, and the excess charge in the BGT could then spread out into the ground, supplying the circuit for that brief period.
Anyone care to comment?
