Abstract

In order to develop a watching system for an aged single person by grasping his or her usage of electricity, we hatched out a method to infer definitely whether a resident directly operated electric appliances and it resulted in a significant increase in electricity consumption or not from total load current of the household, which was averaged at an appropriate interval. Then we evaluated the method by using the total load current measured at 11 households of an actual aged single persons for 1 year (totally 3,724 days) and records on their outing. The results of the evaluation showed an effectiveness of the method.
