electrostatic charge decay can take a LONG time

I analyze this phenonmenon professionally for powders in the pharmaceutical industry and IF there is tribo charging going on the rate of decay will depend on the conductivity of the surface that the charge resides and on the environmental humidity.

Since most dielectrics are extremely good insulators it means that a charge generated there can basically sit there indefinitely. However, if the RH in the room is high you will get dissipation relatively quickly. If the RH is low it can take a LONG time to dissipate that charge effectively. Does this have an effect on cables??? Don't really know.
