Scenario of Transmission and Distribution Losses

 Scenario of Transmission and Distribution Losses The power plants typically produce 50 Hz alternating current electricity with voltages between 11 kV and 33 kV. At power plant site the three phase voltage is stepped up to higher voltage for transmission through conductors strung on towers. High voltage and extra high voltage transmission is the next … Read more
