Traditionally structures have been protected by the use of air terminals (Franklin Lightning Rods) and a network of downconductors connecting to an integrated grounding system.
Resistance-reducing agent does not reduce the impulse grounding resistance under large lightning current.
降阻剂并不能降低接地极在强雷电流下的冲击接地电阻。
