There are 2 types of lightning that we need to prevent that : direct lightning and Surge

 I. Prevention of Lightning

1. Lightning passive ( also called lightning classic metal )

Often used one or more metal rods placed on the roof of the building and the lightning conductors connected to the grounding system . The biggest disadvantage is the classic metal fitting protective radius low , should be used more evenly iron bar on the scope of the work involves increasing copper ceiling and other costs are going up , not to mention reliability less because of oxidized metal .

2. Surge Protection for camera systems ( CCVT )

 Surge Protection Solutions for the camera like lightning to the electricity system , however , external lightning protection to lightning source must also own camera for the signal over coaxial cable .

 

3. Surge Protection for the network :

Surge Protection Network .

    Computer network system includes a server ( Server ) , workstations and other devices such as modem , switch ... The system is very susceptible to lightning spreading may cause electric shock (for people ) and damaged (for with equipment ) , severely affecting business operations of the list now . So to avoid electric shock and protect equipment we need to install equipment Surge excision for this device .


 

 

 

    Collections Surge filters on data lines are located before the input of the modem , switch, hub ... and before entering the computer . We have split duties lightning to the maximum to ensure the safety of the equipment and the lightning led to the grounding system . Earthing system must reach land under 4 Ohm resistors .
