Problems solved by technology
[0003] At present, there is no unified standard user-side power distribution system solution in the Shanghai power market, but the types of customer equipment are relatively complicated, the individual requirements are relatively strong, and the market is becoming more and more open, which brings difficulties to user-side power distribution
Moreover, because the power measuring equipment is not independent, there is also a hidden danger of power theft, which is likely to increase the line loss rate
In addition, there are certain unsafe factors in the existing wiring method
