The Analyse And The Evaluation Of The Power Frequency Electric Field And Magnetic Field Around The City

Along with the development of the electric network and the improvement of people's quality of life,more and more people pay close attention to high tension transmission line,the environment of the electromagnetism around the transformer substation,also the infection of the electric field and magnetic field to people's health. From this article ,we improve on the electric establishment ,just like 110kV,220kV transmission line,cable line,the calculate and the actual measurement of the electric field and magnetic field around the transformer substation, compare to the international standard and inland standard ,we make the evaluation of the city electromagnetism environment.
