Lightning Protection System

The main and most effective measure for protection of thatch structures against physical damage is considered to be the lightning (LPS)


An external LPS is intended to:

Intercept a lightning flash to the structure (with an air termination system)


Conduct the lightning current safely towards earth (using a down-conductor system)


Disperse the lightning current into the earth (using an earth-termination system)


If lightning protection is to be added to an existing structure every effort should be made to ensure that it conforms to the principles of Sans 62305-3 The design of these types and location of an LPS should take into account the features of the existing structures.


An internal LPS prevents dangerous sparking within the structure using either equipment bording or a seperation distance (And Electrical Insulation) Between the external LPS components and other electronically conducting elements internal to the structures.
