Lightning can harm buildings, devices, wiring, and living beings, whether it hits directly or indirectly. To minimize these risks, safeguarding against lightning has become crucial.
The way voltage and current behave affects how lightning protection works. To enhance a distribution substation’s resistance to lightning, we cautiously choose the characteristics of the connected arresters. Thus, we ensure that the lightning current is shared adequately and reduces the chances of arrester failure. The location of surge arresters and the length of underground cables significantly impact the lightning resistance of high-voltage/medium-voltage substations.
Knowing the principles of lightning damage and risk factors allows us to reduce losses using methods like installing lightning protection devices such as lightning straps, rods, and meshes, grounding grids, surge protectors, metal shielding, fire protection, and warning signs.
To ensure safety for people, devices, and buildings, HY considers the economic efficiency and feasibility of these protection measures.
