PRINCIPLE（原理）

  The lightning event counter functioning principle relies on a device located around the down-conductor,

which has also a transformer-performance,and a conditioning system that easies the counting a device

activation.（將避雷接地線穿過計數器的中間圓孔，當雷擊時，大量電流建立的磁場會經過計數器的鐵芯及線圈，在鐵芯及線圈會產生感應電壓及電流，當電壓超過預設數據時，會推動計數器跳一碼.）
