POWER STRIP CURRENT-CORRECTION-EQUATION CALCULATION METHOD, CURRENT MEASUREMENT METHOD, POWER MEASUREMENT METHOD, MANUFACTURING METHOD, POWER STRIP, AND CURRENT MEASUREMENT SYSTEM

摘要

A power strip current-correction-equation calculation method has: a first measurement step of, by using current measurement units for measuring the respective currents flowing through the plurality of socket portions of a power strip, measuring the voltage values in the respective current measurement units when no currents flow through the socket portions of the power strip; a second measurement step of measuring the voltage values in the respective current measurement units when current flows through any one of the socket portions; and a correction equation calculation step of calculating the correction equation given by the inverse matrix of a matrix in which the differences between the voltage values obtained in the second measurement and the voltage values obtained in the first measurement are used as elements.
