1. Voltages
電壓
a. General.
概述
Refer to ANSI Standard C84. 1 for voltage ratings for 60 Hz electric power systems and equipment. In addition, the standard lists applicable motor and motor control nameplate voltage ranges up to nominal system voltages of 13.8 kV.
60Hz電力系統和設備的額定電壓，參見ANSI標准C84.1。另外，該標准列出了標稱系統電壓不超過13.8kv的適用發動機（電機）和發動機控制銘牌電壓。
b. Generators.
發電機
Terminal voltage ratings for power plant generators depend on the size of the generators and their application. Generally, the larger the generator, the higher the voltage. Generators for a power plant serving an Army installation will be in the range from 4160 volts to 13.8 kV to suit the size of the unit and primary distribution system voltage. Generators in this size range will be offered by the manufacturer in accordance with its design, and it would be difficult and expensive to get a different voltage rating. Insofar as possible, the generator voltage should match the distribution voltage to avoid the installation of a transformer between the generator and the distribution system.
發電機及其應用。通常，發電機越大，則電壓越高。供應軍事裝置的電廠發電機電壓在4160伏到13.8千伏，適合機組和一級（主要）配電系統電壓。該規格範圍的發電機由製造商根據其設計予以提供。選用其它額定電壓則比較困難而且價格昂貴。發電機電壓應盡可能與配電電壓匹配，省去在發電機和配電系統之間加裝變壓器的需要。
c. Power plant station service power systems.
電站供電系統
(1) Voltages for station service power supply within steam electric generating stations are related to motor size and, to a lesser extent, distances of cable runs. Motor sizes for draft fans and boiler feed pumps usually control the selection of the highest station service power voltage level. Rules for selecting motor voltage are not rigid but are based on relative costs. For instance, if there is only one motor larger than 200 hp and it is, say, only 300 hp, it might be a good choice to select this one larger motor for 460 volts so that the entire auxiliary power system can be designed at the lower voltage.
蒸汽發電電站內部供電電壓與發動機規格有關，而與電纜布線距離的關系稍微遠一點。抽風機和鍋爐給水泵的電動機規格通常決定了電站的最高供電電壓。發動機電壓選擇規則並不嚴格，而是根據相對成本。例如，如果只有一台200hp以上的發動機，比如只有300hp，那麼最好將該更大的發動機用於460伏，從而整個輔助電力系統（廠用電系統）可以在更低的電壓水平進行設計。
(2) Station service power requirements for combustion turbine and internal combustion engine generating plants are such that 208 or 480 volts will be used.
關於燃氣輪機和內燃發動機發電廠的電站供電電壓要求，將使用208或480伏。
d. Distribution system.
配電系統
The primary distribution system for an Army installation with central in house generation should be selected in accordance with TM 5-811 -l/AFM 88-9.
中心內部發電（這句不能肯定）的軍事裝置的一級（主要）配電系統按照TM 5-811-1/AFM 88-9選擇。

❹ 電力的英文翻譯是什麼

electricity是電流, 電, 電學之意
power在物理學上指能量、動力、功率之意
而electric power是指電力, 電功率。回
所以，根答據你的翻譯要求，答案為electric power為妥。
