テスト パイル 保護 パラメータ 検出

陰極 保護 テスト 杭 しなければならない ある 設置 する 決定する 位置, 電流 そして 抵抗 of the structure. For this reason, no other better measuring device is available. For pipeline potential test piles, 1 to 2km is enough. 一般的に, one pipeline current measuring pileing piles required for every 5 measuring piles. In densely built areas in cities and towns, the distance between potential measuring piles is about half a kilometer. On the Contrary, it is necessary to set ground electrical insulation measuring piles on the buried electrical insulation parts. At the intersection with the DC traction system, measuring piles should also be set. If necessary (such as on a high-ohm fixed surface), a fixed measuring point for measuring the potential of the structure should be set.
