State Grid published the first specification of Smart Electricity Meter ( SE-meter) in 2009, with some addi -tional functions and features added in 2013.As SE-meter gains more and more popularity over the years , it has be-come increasingly clear that the low power consumption and high reliability are becoming more and more important in the operations of SE-meters.The self-power consumptions of SE-meters and the corresponding power supply circuits have been analyzed in detail in this paper .The designs of wide voltage , high reliability and low-power consumption linear power management IC have been adopted to improve the reliability and cost performance , so as to satisfy the state standard of smart meter.The power consumptions during stand-by mode are reduced to 0.4~0.6 W per SE-meter and the cost of IC in power supply component of smart meter are reduced , which will make great sense for energy sav-ing and emission reduction as well as improve the economic benefit for power supply enterprise .
