But the lightning rod must be reliable grounding, grounding resistance should be less than 10 ohm, if it is to build their own houses, generally do not have a grounding, lightning grounding usually adopts 3 grounding, word order or triangular arrangement, a distance of 5 meters above, the need to spend thousands of dollars, if the building ground is can be directly used flat iron or steel cited in the past so near, estimated to spend hundreds of dollars is enough
In fact, lightning arrester lightning principle is mine, the lightning current into the earth, so that there is no protection equipment lightning flow.The lightning rod is set more than the equipment you want to protect. You only need to know that the height of the lightning rod must exceed a certain height. As you have, the 2~3 meter is enough. The closer the electric plate is, the better the effect is.
