<p>PROBLEM TO BE SOLVED: To provide a small-sized electric energy converter easy in installation work, and capable of monitoring concentratedly electric energies at many measuring points. SOLUTION: A socket 2 fixes an electric energy converter body 1 and connects each wiring 4, 5, 7. A communication line 7 connects the body 1 to an electric energy data collecting personal computer 6 in a network. A current transformer is a split type current transformer 3, and can be installed on a power supply line 10 with an easy work without opening the power supply line 10. When apparatuses, whose electric energies are to be measured, are scattered in a wide region inside factories and offices and the electric energies of each of all manufacturing plants or the like are required to be measured, power consumptions of many plants can be monitored always unifiedly by the personal computer 6 by using a communication function possessed by the body 1. In this way, electric energy measurement is possible by one package, and by using only a communication function as an output method of coulometric data, the internal structure can be simplified and miniaturized.</p> |
