Title:
CURRENT MEASUREMENT DEVICE, CONTROL METHOD AND CONTROL PROGRAM FOR SAME, RECORDING MEDIUM, AND POWER MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/122230
Kind Code:
A1
Abstract:
A microcontroller (23) operates using power from a power supply (21). The microcontroller (23) selects one of a plurality of switching circuits (20), and the current from a plurality of current transformers (CT) flows to the microcontroller (23) through the selected switching circuit (20) and flows to the power supply unit (21) through the unselected switching circuits. The microcontroller (23) performs control such that the selection is carried out successively for each of the plurality of switching circuits (20).
