| 摘 要： | 避雷线对于高压和超高压电网的安全运行具有重要的意义。但是即使在正常运行情况下，避雷线也会感应出电压，从而形成电流，造成电能损耗。文章通过对这一现象的原理进行简单的分析，提出了利用复合阻抗把避雷线和杆塔(地)绝缘起来的方法，来减小电能损耗，从而达到经济运行的目的。此研究利用EMTP程序对这一方法的可行性进行了验证。

| Abstract: | The lightning lines are very important for high voltage and super high voltage electrical grid to run safely. Because there is inductive voltage in the lightning lines, which will produce current, power energy will be wasted in the lightning line, even if the power system runs normally. The article brings forward a way to reduce the power energy wastage by using a multiple impedance between the insulated lightning line and ground, and the feasibility is validated by EMTP in this article. |

| Keywords: | EMTP (Electromagnetic Transient Program) inductive voltage power energy wastage multiple impedances |
