There should be no fewer than ( ) grounding points, which should be evenly distributed around the perimeter of the tank; the distance between these grounding wires should not exceed 18 meters. The impulse grounding resistance of each down conductor shall not be greater than ( ). Answer reply available at: 2 locations ； 10Ω
The metal tank should be grounded to protect it from direct lightning strikes; there should be no fewer than (2) grounding points, which should be evenly distributed around the perimeter of the tank. The distance between these grounding wires should not exceed 18 meters. The impulse grounding resistance of each down conductor shall not exceed (10Ω)
