  "textContent": "The present invention relates to a detecting device (112, 311) and method, and a program which can detect a power state easily at low cost. A current transformer (111c) measures current at a side of a commercial power system from a commercial power supply (152) through a connection point (C) of the commercial power system and a power generation system from a solar power generation system configured to supply power having the same frequency as the commercial power supply (152). A current transformer (111p) measures power at the power generation system side through the connection point (C). A decision value calculator (132) calculates a decision value based on a value obtained through multiplication of a measured value of current through the current transformer (111c) and a measured value of current through the current transformer (111p). A flow detector (133) detects a power flow of the commercial power system based on the calculated decision value. The present invention can be applied to a power measuring system configured to measure power in homes, for example.",
