DEEMED POWER VALUE OUTPUT CURRENT MONITORING DEVICE BY OWN POWER SOURCE SYSTEM

PROBLEM TO BE SOLVED: To provide a current monitoring measurement device capable of safely and easily measuring and excellent in economic efficiency, for visualizing the amount of power consumption on real time for cost reduction by electric energy saving, to provide a measurement device which does not have to carry out direct connection to a power line, and to provide a current monitoring and measuring device, the driving electric power source of which is a self electric power source system without needing 100 V electric power source or electric battery. SOLUTION: This device which is equipped without voltage input terminals like as a conventional watt meter calculates the deemed power value and obtains the integrated value by using the rating voltage of the installation place preset in the CPU memory and the current value detected by the device for realizing saving work and low cost, thus outputting the result to a real time power monitoring system which is a backward system. The electric energy for activating this device is secured by the electromagnetic induction through the current transformers from the power line to be measured, and the unevenness of the power generation is coped with a super capacitor, therefore the external power source or electric battery is not needed.
