Regional energy information including dashboards, maps, data, and analyses. To reduce energy transfers to the environment, the National Grid uses step-up transformers to increase the voltage from power stations to thousands of volts, which lowers the current in the transmission cables. Electrical Transformer: How Does It Work? 9 below for the worlds tallest pylons.). Step-up transformers increase the voltage of the incoming current, while step-down transformers decrease the incoming currents voltage. Comprehensive data summaries, comparisons, analysis, and projections integrated across all energy sources. The pylons connect over 4,500 miles of high-voltage overhead lines across the two countries that's enough to stretch from London to Mumbai. The lower the current, the lower the resistance losses in the conductors. As electricity is transmitted over long distances, there are inherent energy losses along the way. It may sound like an entry in Have I Got News For You?, but today the website Pylon of the Month is a must-see for pylon lovers, as is the Pylon Appreciation Society. Why are the birds not electrocuted when they sit on the power lines?
