Real-time phase shifting technology solves the problem of power loss due to voltage loss
Summary:The phenomenon of one phase or two phase or even three phase fuses of voltage transformers often occurs in high power metering devices with high power supply and high meter.However,the probability of single-phase fuse is higher than that of polyphase fuse.The reasons for this phenomenon are many but can not be determined at the moment,the usual treatment method is that the power failure to replace the fuse,the basic can be restored to normal.In this paper,we study a method to generate the missing voltage by using the normal phase voltage as the reference reference under the condition of no power outage,and temporarily restore the missing voltage caused by the fusing of the fuse,so as to solve the practical problem of less power metering.
