STATIC ELECTRICITY

**Definition:** This place covers:

Means for preventing the formation of or removal of electrostatic charges in general, not otherwise provided for.

Using naturally-occurring electricity (e.g. lightning)

**Glossary:** - Corona discharge or brush discharge: Discharge from a conductor when the potential difference between it and its surroundings exceeds a certain value but is not enough to cause a spark or an arc. - Spark gaps: Enclosed or non-enclosed discharge devices having cold electrodes and used exclusively to discharge a quantity of electrical energy in small time duration. - Coupling devices: Devices having two or more parts specially adapted so as to be capable of ready and repeated physical engagement or disengagement, without the use of a tool for the purpose or establishing or breaking an electrical path. - Electrostatic charge: They are used as synonyms for the electric charge at rest on the surface of an insulator or insulated body.
