Why is electricity transmitted at high voltage?
2025-08-17Electricity is transmitted at very high voltages to drastically reduce energy loss and to improve efficiency. This principle is governed by the basic physics of power loss, which is directly proportional to the square of the current ().
Power (P) is the product of voltage (V) and current (I). For a given amount of power, if you increase the voltage, the current must decrease proportionally. By transmitting power at ultra-high voltages, the current is kept very low, which in turn minimizes the heat generated in the conductors due to resistance. This means that a much greater percentage of the generated power reaches its destination, which is critical for long-range transmission projects that cross vast distances.
