Webvoltage to ground is over 50 kilovolts (50,000 volts). The higher the voltage, the greater the distance that is needed between the lines and the workers. (See Occupational Safety and Health Administration (OSHA) Title 29 of the Code of Federal Regulations (CFR) Part 1926.1408.) TABLE A -- MINIMUM CLEARANCE DISTANCES Voltage WebWe can calculate the minimum clearance for the transmission line of different voltages using this IE rule. The minimum ground clearance for a 33 kV transmission line is 5.2 meters. Now, if we calculate ground clearance of 400 kV, the additional voltage above 33 kV is; Now, we calculate the number of times the voltage 367 kV is higher than 33 kV.

WebIn a residential distribution system, a primary, high-voltage line connects to a step-down transformer, typically recognized as a cylinder, perhaps two feet high and one foot in … WebBoth electric and magnetic fields depend on the clearance of the line. The minimum ground clearance of a 400 kV line is 7.6 m, dropping to 5.2 m for low-voltage distribution lines. See a full listing of minimum clearances for high-voltage lines under different circumstances. But in reality it is rare for lines to be this low, and the ground ... the weathervane motel in lancaster pa
