Title:
POWER MEASUREMENT SYSTEM
Document Type and Number:
Japanese Patent JP2016085121
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a band width necessary for a communication path between a measurement device and an arithmetic device.SOLUTION: A power measurement system comprises: a current detection unit for detecting a current flowing in a load circuit connected to a power distribution system; a measurement device for outputting a voltage signal equivalent to a voltage value of the power distribution system in a predetermined cycle; and an arithmetic device to which the voltage signal is input from the measurement device and a current signal equivalent to a current value detected by the current detection unit is input from the current detection unit, and which integrates a value obtained by multiplying the voltage value by the current value for a prescribed period to determine the value as a power value of the load circuit, and outputs the power value to the measurement device in a cycle longer than a cycle in which the voltage signal is supplied.SELECTED DRAWING: Figure 3
