The minimum clearance between the ground and a 220 kV line is 7.0 meters. This is to ensure that people and objects do not come into contact with the high voltage wires and are not electrocuted. The clearance is also necessary to prevent damage to the wires and equipment from falling objects.<\/p>\n
Option A is incorrect because it is the minimum clearance for a 132 kV line. Option B is incorrect because it is the minimum clearance for a 115 kV line. Option C is incorrect because it is the minimum clearance for a 69 kV line. Option D is correct because it is the minimum clearance for a 220 kV line.<\/p>\n
The minimum clearance for a power line is determined by the voltage of the line. The higher the voltage, the greater the clearance required. This is because the higher the voltage, the greater the electrical field strength around the wires. The electrical field strength can cause a person or object to become electrocuted if they come into contact with the wires.<\/p>\n
The minimum clearance is also necessary to prevent damage to the wires and equipment from falling objects. If an object falls onto a power line, it can cause the wires to break or arc. This can create a fire or explosion.<\/p>\n
It is important to always stay away from power lines. If you see a power line that is down, do not touch it. Report the downed line to the power company immediately.<\/p>\n","protected":false},"excerpt":{"rendered":"
