The above is the basic requirement of a single system, that is to say, the basic requirement of the power provided is the sine wave that meets the power frequency and amplitude requirements, and the three-phase system also needs three-phase balance. In addition, modern power quality also includes voltage fluctuation and flicker, waveform distortion and all transient voltage phenomena, such as voltage peak interference, voltage surge and drop, voltage interruption, etc.
