The protection against overvoltages in an electrical installation is vital to guarantee peoples safety and avoid short and long term damages to equipment. A large majority of the installations are protected against overloads and derivations, but the installed devices do not protect against transient overvoltages (due to lightning) and permanent overvoltages (for example due to neutral failures).
More and more buildings and houses have electronic devices that allow for a more efficient and comfortable home: thermoregulation, sophisticated security systems, all kind of automations, remote controllers, energy management systems, several interconnected devices…There is no doubt in there being a trend for domotised homes which will increase, given how these technologies mean an important improvement in the quality of life.
Due to the characteristics of public lighting, they require specific protection against transient overvoltages. The ATSOCKET protectors of Aplicaciones Tecnológicas were designed ex profeso to be used in outdoor luminaire installations, although they have other applications, given how it is possible the connection in the interior of the trunking which feed the socket powers.
In residential sector and in small tertiary business, it is recommended to protect correctly the installations against both permanent and transient overvoltages. Usually, in such cases (houses, business, worshops, restaurants, etc), are limited by a lack of space. The most appropriate solution is to use permanent and transient overvoltage protectors in the same device.
