中译英：
reactive翻译有时高电压系统可能是辐射式的，低电压系统可能进入系统之内被连接。另外的一个方法是将两种系统连接起来使用。
（1） 二次环绕系统
大多数情况下载变压器之间用点把不同的负荷连结到系统中也是很方便的。这种系统叫做二次环绕系统。NEC450型号的设备给出了特殊的关于最终极的环绕系统。
（2） 接地系统
一般地说，大多数的电力系统都要置于地面。放在地面上的目的是将限制由闪电而发出瞬间的励磁涌流和意外接触较高的电压所引起的过电压。当接地故障发生时，为保证过流设备工作，必须设置系统接地以提供最小阻抗通路。设备就不会受到不正常的电流干扰。
英译中：
The basic purpose of a shunt capacitor bank is to increase the local circuit voltage or improv
e the load power factor carried by the circuit. Many large capacitor banks are switched on and off as the system need for reactive kilovolt amperes changes. System requirements govern whether a certain bank should or should not be switched. If the voltage at the capacitor would be too high during light load, some or all of the capacitors are switched off. Very large banks are usually switched in steps.
A synchronous condenser is nothing more than a synchronous machine running at synchronous speed with no mechanical load. The condenser has a control circuit that controls the field excitation to provide voltage control. When the system voltage starts to fall below the desired values, the control circuit will automatically increase the field excitation which causes the synchronous condenser to supply vats to the system. This will increase the system voltage at the point.
