| Abstract: | This paper introduces the design scheme which uses network clock to determine the daily timing error of smart meters for optimization and integration of measuring resources. The network clock system incor- porates precision time base, shaping circuit, frequency dividing circuit, driving circuit, photoelectric isolating circuit and time error treatment system. The scheme is especially suitable for the smart meter calibrating in- struments that are extensively used. |
