Hi, I'm working on one problem of prognostic of machinery failure. I want to use RMS of three-phase voltage as parameter for prediction. I would like to know how to compute the RMS of voltage of a 3-phase motor ? In fact, I have a 1000 samples for each voltage phase ( http://...

Under the conditions of both the ideal sinusoidal wave voltage and practical non-sinusoidal wave voltage, the said stabilizer can ensure the stabilizing accuracy of output voltage in true effective value.张树华
3. 例子 让我们考虑一段交流电流,其电压值在−240V∼240V之间,频率为60Hz,试计算这段电流的有效电压(RMS voltage). RMS=(2.88∗104)12≈169.7V 参考 ^A为振幅,ω为角频率,φ为相位,B为数值偏移 ^此处phase以及numerical migration均为0 编辑于 2024-02-23 10:33・IP 属地北京 ...

On the other hand, the implementation can fall into offset voltage error. Furthermore, the information of the output voltage phase is hidden for the control as well, making the synchronization of a 3-phase setup not trivial. This paper explains the concept, design and implementation of the ...
