| 2. | The maximum switching surge level used in the design of a substation is either the maximum surge that |
| 在变电站设计时所采用的最大操作过电压是系统中可能出现的最大操作过电压或是避雷器的保护水平,而避雷器保护水平就是被避雷器所允许进入变电站的最大操作过电压。 |

| 3. | Line reactors almost always can reduce line-switching surge magnitudes. |
| 线路电抗器几乎总是可降低线路操作过电压值。 |
|
|
| | |
| 4. | This results from the fact that the switching surge strength of most external insulation is lower than |
| 这是由于,大部分外绝缘的操作冲击强度要低于相应的雷电冲击强度,也由于操作冲击强度并不随空气间隙距离的增加而线性增加。 |
|
|
| | |
| 5. | The switching surge insulation level (SIL) is the dominant factor on EHV systems. |
| 操作冲击绝缘水平(SIL)对超高压系统来讲是决定性因素。 |

| 6. | superimposing on the normal system voltage, the total being known as the restriking voltage and constituting a switching |
| 出现于电路中的电压由一高频分量迭加在正常系统电压上所组成,总称为重燃电压,且引发操作过电压。 |
