Lagging Power Factor Lagging power factor in AC circuits (a power factor of less than 1.0) is caused by inductive loads, such as motors and transformers, which cause the current to lag behind the voltage. See Power Factor.
滞后功率因数 交流电路中的滞后功率因数（小于1.0）是由感应负荷引起的，例如发动机、变压器，使电流滞后于电压。（参照功率因数）

Leading Power Factor Leading power factor in AC circuits (0.0 to -1.0) is caused by capacitive loads or overexcited synchronous motors which cause the current to lead the voltage. See Power Factor.
超前功率因数 交流电路中的超前功率因数(0.0 to -1.0)是由电容负荷或者过励的同步电动机引起的，使电流超前于电压。（参照功率因数）

Line-To-Line Voltage Line-to-line voltage is the voltage between any two phases of an AC generator.
线电压 线电压是指交流发电机任何两相间的电压。

Line-To-Neutral Voltage In a 3-phase, 4-wire, Y-connected generator, line-to-neutral voltage is the voltage between a phase and the common neutral where the three phases are tied together.
相电压 在三相四线星形连接的发电机中，相电压是指三相连接点与每相之间的电压。

Load Factor The load factor is the ratio of the average load to the generator set power rating.
负荷系数 负荷系数指的是机组的平均负荷与额定功率之间的比率。

Load Shedding Load shedding is the process by which the total load on a paralleling system is reduced, on overload of the system bus, so that the most critical loads continue to be provided with reliable electrical service.
卸载 在超载的系统母排上，并联系统的总负载被降低的过程称为卸载，以确保最关键负载获得可靠的电力供应。

Low Voltage AC system operating voltages from 120 to 600 VAC.
低压 交流电系统中从120到600 VAC的电压称为低压。
