5. Lightning-Proof Design
The regional surface displacement monitoring system of the ground disaster
monitoring uses lightning rods for direct lightning protection, single power
supply arrester and communication cable arrester for inductive lightning
protection.
5.1 Direct lightning protection
As the specific lightning protection method required, the distance between the
lightning rod and the protected object must be not less than 3m. The height of
lightning rod is determined in accordance with the ‘Rolling Ball Rule’ and can
be roughly calculated.
