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. WebThe positions of the conductors relative to each other stays the same throughout the length of the line, but the clearance above ground varies from span to span and along each span as the conductors sag. The minimum clearance to ground for 400 kV is 7.6 m but is rarely found in practice. When we want a typical clearance we often use 12 m.
