Abstract: The present invention relates to a detecting device and method, and a program which can detect a power state easily at low cost. A current transformer measures current of a commercial power system from a commercial power supply through a connection point of the commercial power system and a power generation system from a solar power generation system that supplies power having the same frequency as the commercial power supply. A current transformer measures power at the power generation system side through the connection point. A decision value calculator calculates a decision value based on a value obtained through multiplication of a measured value of current through the current transformer and through the current transformer. A flow detector detects a power flow of the commercial power system based on the calculated value. The present invention can be applied to a power measuring system for use in homes, for example.
