Study on electric field distribution characteristics of the maintenance area when UHV AC transmission line crossing 220 kV tower

Study on electric field distribution characteristics of the maintenance area when UHV AC transmission line crossing 220 kV tower

With the rapid development of China's power grid, it is becoming increasingly common that the multi-circuit overhead transmission lines cross over each other. It is important to design the lines' configuration reasonably and evaluate whether the power-frequency electric field meets the nat...
