A first power receiving apparatus observes a power transfer signal from a power supply apparatus, and detects whether power transfer is being performed between the power supply apparatus and a second power receiving apparatus. When the power transfer is being performed between the power supply apparatus and the second power receiving apparatus, a waveform of the signal is deformed with a predetermined pattern. The second power receiving apparatus detects deterioration in power which is received from the power supply apparatus and detects whether the waveform of the signal changes with the predetermined pattern within a predetermined time after detecting the power deterioration. When detecting the change in the waveform of the signal with the predetermined pattern, the second power receiving apparatus determines that the first power receiving apparatus is in a power suppliable range of the power supply apparatus.
