The voltage rating of these resistors must be at least equal to the test voltage.
这些电阻器的电压额定值必须至少等于测试电压。If the insulation is to be as well protected after it is reduced, the arrester rating must be correspondingly reduced.
若绝缘减少后仍同样地能被保护，那末避雷器额定值也必须相应降低。Do not exceed the speed in revolutions per minute (RPM) rating of any grinding wheel or disk.
不可超过任何砂轮片或转盘的每分钟转数（RPM）额定值。31 rated voltage: The voltage to which operating and performance characteristics of a heating device is referred.
额定电压：加热装置参考的运行和性能特性电压。However, to be useful, they must be characterized for capacitance value, voltage rating, temperature coefficient, and leakage resistance.
然而，要使用电容器就必须明白其特性：包括电容值、额定电压值、温度系数以及泄漏电阻等。the voltage cannot be regulated in a large range, and the optimal range of the voltage regulation is less than 10% of the rated voltage.
电动机调压调速的范围不能太大，电压调整的最佳范围为额定电压的10%以内。State-of-the-art and low noise: The vortex LZW series wind generator has low noise due to its low rated speed.
噪音小、技术含量高旋风LZW系列风力发电机，由于额定转速低，它的噪音很小；By this method, the total harmonic distortion (THD) of the ac line current is only 4. 5% at the rated output power.
藉由此方法，输入电流的总谐波失真在额定负载时仅有4.ASME capacities are steam pressure ratings and do not reflect the CSA temperature relieving capacity of the valves for selection purposes.
ASME流容是蒸汽压力额定值，并不代表阀门在所选择的用途中CSA温度泄放能力。
