Gas-filled surge arresters are classical components for protecting the installations of the telecommunications. It is essential that IT and telecommunications systems -with their high-grade but sensitive electronic circuits – be protected by arresters. They are thus fitted at the input of the power supply system together with varistors and at the connection points to telecommunication lines. They have become equally indispensable for protecting base stations in mobile telephone systems as well as extensive cable television (CATV) networks with their repeaters and distribution systems.

These protective components are also indispensable in other sectors:

• In AC power transmission systems, they are often used with current-limiting varistors
• In customer premises equipment such as DSL modems,WLAN routers, TV sets and cable modems
• In air-conditioning equipment

The integral black-box concept offers graduated protection by combining arresters with varistors, PTC thermistors, diodes and inductors to create an ideal solution for many applications.

There is a common intermediate configuration, when both electrodes are located on the same probe, but the return electrode is much larger than the active one. Since current density is higher in front of the smaller electrode, the heating and associated tissue effects take place only (or primarily) in front of the active electrode, and exact position of the return electrode on tissue is not critical. Sometimes such configuration is called sesqui polar, even though the origin of this term in Latin (sesqui) means a ratio of 1.5

Kingtronics (www.kingtronics.com ) sell 2-Electrode arresters and 3-Electrode arresters. Surge arresters are designed to protect electrical equipment from damaging effects of spikes and transients caused by lightning, utility switching, isolation arcing, electrical motor cycling, or any other sudden change in electrical power flow on incoming AC power lines.

A typical surge arrester consists of disks made of zinc oxide material, sized in cross-sectional area to provide the desired energy discharge capability, and in axial length proportional to the voltage capability. These disks are placed in porcelain enclosures to provide physical support, aid in heat removal, and are sealed for protection from contamination in the electrical environment.
