ELECTRONIC WATT-HOUR METER

摘要

PROBLEM TO BE SOLVED: To provide an electronic watt-hour meter which achieves the easy reduction in constituent materials of a current detector and the improvement of assembling workability of the current detector.SOLUTION: An electronic watt-hour meter includes a housing 8 which is provided with: a terminal part constituted by an input terminal supplying power, and an output terminal supplying the power to a load; a voltage detector detecting a voltage applied to the input terminal; a current detector 5 detecting a current flowing between the input and output terminals; and a power calculation part for measuring electric energy from the voltage detected by the voltage detector and the current detected by the current detector. The current detector 5 has such structure that a core 11 and a Hall element 13 as current detection elements are integrally mounted on the housing 8 by using a hot melt adhesive 15.
