These systems must be used to safely transfer lightning strikes to the ground in unprotected locations with critical elements, such as mines. Another important aspect to remember is that each facility is established on different terrain and structural conditions. Considering the facility conditions, the most suitable external lightning protection system listed below should be installed.

When lightning strikes the ground, underground systems have no chance to escape this impulse; therefore, LV surge protection systems must be used at every point. Products with high IP ratings and protection capacities must be selected. Especially 3\u201312\u201324 V systems can be directly disabled, which directly affects worker safety in adverse situations. To prevent negative conditions in mines, low-voltage surge arresters must absolutely be used.
