How is Power Transmission carried out?

The large shift of electrical energy, from power plants to substations situated close by population hub is called theElectric power transmission or "high voltage electric transmission" and is transmitted through overhead power lines. Electricity is spread at high voltages (110 kV or above) to trim down the energy lost in long distance transmission.  When interrelated with one another, transmission lines turn into high voltage transmission networks. In the US, these are typically denoted to as "power grids" , in UK the network is known as the "national grid."
