In modern households, electrical devices and systems make life easier:
- TVs, stereo and video equipment, satellite systems
- Electric cookers, dishwashers and washing machines, dryers, refrigerators/freezers, coffee machines, etc.
- Laptops / PCs / tablet PCs, printers, smartphones, etc.
- Heating, air-conditioning and ventilation systems
Insurance coverage alone is not enough
Surges can damage or even completely destroy these devices, resulting in a financial damage of some 1,200 USD. In addition to this financial damage, surges often cause immaterial damage such as loss of personal data (photo, video or music files). The consequences of surges are also unpleasant if the heating system, shutters or lighting system fails due to damaged controllers. Even if the household insurance settles the claim, personal data is lost forever. Claim settlement and replacement take up time and are annoying.
Therefore, it is necessary to install a residential buildings surge protection system!
First step: System protection
The first step is to consider all lines leaving or entering the building: Power supply / telephone / lighting lines, TV / SAT connections, connections for PV systems, etc.
In residential buildings, meters and sub-circuit distribution boards are often placed in one enclosure. For this purpose, LSP comes in different versions to protect both the installation and the terminal devices on the power supply side, even in case of direct lightning strikes. LSP can be provided for the telephone connection e.g. via DSL / ISDN. This arrester is sufficient to ensure safe operation of the DSL router. LSP protect the controller of the heating system, which is often located in the basement.
If there are further distribution boards, LSP surge arresters are to be installed.
Second step: Protection of terminal devices
The next step is to protect all terminal devices, which are fed by several power supply systems, by installing surge protective devices right at their inputs. These terminal devices include TVs, video, and stereo equipment as well as alarm and video surveillance systems. The antenna amplifiers can be protected by means of LSP.
The cascaded use of surge protective devices prevents damage and is more economical than you may think.
