Application Notes

EAP-030046

It has been said that if you use buried cables, then that is enough protection from lightning. Is this a true statement?

No, it's because buried cables are also vulnerable to the unpredictable power of lightning.

A buried cable does not have as much protection from induced lightning as one might expect, because underground soil easily transmits an electromagnetic field which occurs during a lightning discharge. Also, the high lightning current that is being discharged to ground by the lightning rod can find its way to the buried cables located in the ground.
