A great diversity of the nominal voltages in power networks can be explained based on the sizes and shape of the fed zone. To find the reason of such diversity, some assumptions should be made: the variation in parameters is continuous, the voltage is constant, the electricity consumers are ...
aAlternative actions must be deleloped 供选择的行动必须是deleloped[translate] aThe nominal supply voltage and frequency are the declared or any of the declared voltages or frequencies for which the EUT is designed. 有名无实的电源电压和频率是EUT设计的宣称或其中任一宣称的电压或频率。[translate]...
• Line-to-line voltages ULL = 1560 V • Line-to-ground voltages ULG = 1100 V The DR. motors can therefore be used with the normal winding on frequency inverters with up to 500 V. If a DR. motor is operated with a frequency inverter supplied with 600 V or 690 V, or the DC ...

The capacitor for rated voltages in excess of 1000 V contains two wound plastics films coated with metal layers, with the foils containing metal-free edge strip on opposite longitudinal sides. The metal layers are contacted at the front side of the coil by hot sprayed films. Both metal layers...
Live-line washing systems for power installations with nominal voltages above 1kV - Part 2: Specific national requirements (national annexes to EN 50186-1:1998); German version EN 50186-2:1998 + A1:2019doi:DIN EN 50186-2
Furthermore to achieve a flexible design this work uses the phase shift between input and output voltages to control efficiency, peak switch voltage and peak switch current then the value of circuit elements and the tradeoffs for every choice are discussed in details and a design guideline is ...
