Static electricity refers to the build up of electric charge on the surface of objects. The static charges remain on an object until they either bleed off to ground or are quickly neutralized by a discharge. Static electricity can be contrasted with current (or dynamic) electricity, which can be delivered through wires as a power source.[1] Although charge exchange can happen whenever any two surfaces come into contact and separate, a static charge only remains when at least one of the surfaces has a high resistance to electrical flow (an electrical insulator). The effects of static electricity are familiar to most people because we can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static 'shock' is caused by the neutralization of charge.
Da come spiega qui, l'energia statica deve essere scaricata a terra e quindi messa a terra = grounded
Penso sia giusta la traduzione grounded

forse questo termine è piu generico e comunque è il contrario di static electricity
