Installation Of The Lightning Earth - Lightning Protection International Stormaster ESE 15 Installation Manual

Installation of the Lightning Earth

Before installation of the lightning protection earth, consult site drawings of underground
services so that these are not damaged during installation of the earthing system.
Earth DC resistance (typically ‹10 ohms) and impedance (typically ‹30 ohms) is required for
successful operation of LPI Stormaster ESE.
LPI recommends the installation of a radial lightning earth as shown in figure 10.
∆
It is recommended to install a 3 x 10 metre length radial trench
∆
Each radial should consist of a trench (Approx: 500 mm Deep x 200 mm wide x 10 m length)
∆
An earth rod should be driven at the end of each trench
∆
All rods should be interconnected through the use of 25 x 3 mm copper tape. The use
of earth rod clamps to fix the tape to rods is recommended
