Title:
結線状態診断装置および結線状態診断方法
Document Type and Number:
Japanese Patent JP5370566
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To obtain a wire connection state diagnosis device that can detect a wrong connection to a power line of a power measurement part.SOLUTION: The wire connection diagnosis device has: electric current measurement means that measures a current value of the power source line to be supplied into a dwelling house; and voltage measurement means that measures a voltage value of a power source line. In a power measurement part in which the measured current value and the measured voltage value are integrated to calculate a measurement power value, a connection state to a power source line of the current measurement means is diagnosed by comparing an estimated power value calculated from an operation state of a home appliance connected to the power source line with the measured measurement power value.
