ELECTRIC POWER MEASURING SYSTEM

摘要

Embodiments of an electric power measuring system capable of computing accurate electric power information using a low voltage measuring instrument in a small-scale electric power system are provided. The electric power measuring system may include a first measuring instrument for measuring and detecting a current and a zero-cross point from a distribution line and for generating and outputting current information of the distribution line from the current and the zero-cross point, and a second measuring instrument for computing electric power information of the distribution line according to a voltage thereof and the current information output from the first measuring instrument.
