What level of protection do you require?

How many lightning induced hazardous overvoltages can you expect in a year?

Do you need surge protection?

These questions can be answered by performing a lightning risk analysis and the results will be dependent on your location, soil type, number and length of data/mains lines coming into the building and the size of the structure etc.

Use our simple on-line Risk Analysis (BS6651:1999) to find out. Note that this standard was superseded on 31st August 2008 by BSEN62305. The Risk analysis system is currently being updated to cover this new standard but in the meantime this system can still be used to evaluate a site and calculate the risk of a lightning induced over voltage.
