It is important to discharge at a slow rate, therefore a resistor should be used in grounding the mat. The resistor, as well as allowing high-voltage charges to leak through to ground, also prevents a shock hazard when working with low-voltage parts. Some ground mats allow one to connect an antistatic wrist strap to them. Versions are designed ...
In aircraft, electrical bonding prevents static electricity build-up that can interfere with radio and navigational equipment. Bonding also provides lightning protection by allowing the current to pass through the airframe with minimum arcing. Bonding prevents dangerous static discharges in aircraft fuel tanks and hoses. [3]
For example, a control panel door may have a bonding jumper across the hinges so that the metal door is effectively connected to ground, since the hinges may not provide a reliable contact. Temporary bonding jumpers are used in the handling of flammable liquids and gases, so that static charge on a vehicle or portable tank does not ignite ...
Static buildup, as induced by friction for example, such as when wind blows onto a radio mast, is dissipated to the Earth. [2] In the event of a surge, a lightning arrester , a surge arrester or a surge protection device (SPD) will divert the excess current to the Earth before it reaches an appliance.
Symbol for an ESD protection device – EPA Alternate warning symbol Symbol of an ESD grounding point for all components. An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors.

A static dissipative mat that rests on a conductive surface (commonly the case in military facilities) are typically made of 3 layers (3-ply) with static dissipative vinyl layers surrounding a conductive substrate which is electrically attached to ground (earth). For commercial uses, static dissipative rubber mats are traditionally used that ...
Effectiveness of the shielding of a static electric field is largely independent of the geometry of the conductive material; however, the static magnetic fields can penetrate the shield completely. In the case of varying electromagnetic fields, the faster the variations are (i.e., the higher the frequencies), the better the material resists ...
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]
