Advantages of High Voltage Transmission  The advantages of High Voltage Transmission  for bulk power transfer are as listed below: 1. Size and cost of the conductor is reduced. The amount of apparent power to be transmitted is given by For the bulk power transmission, the amount of apparent power to be transmitted is large. Hence, from the relation We can say that as the transmission line voltage increases, the amount of the current flowing through line decreases. Now, since the (area of cross section of conductor) is directly proportional to the line current. Hence, the size and cost of the conductor decreases.  2. Transmission line loss will be reduced. The power loss in the transmission line is given by As the magnitude of line current reduces, due to increase in transmission line voltage, the power losses in the line also reduces. 3. Transmission line efficiency will increase. Since the transmission line losses reduces, the transmission efficiency increases. 4. Maximu...
