    • A parallel reading method between a concentrator and a watt-hour meter is disclosed. The parallel reading method between the concentrator and the watt-hour meter according to the present invention comprises the following steps: a) a concentrator modem determines each phase of three-phase power which is supplied from the concentrator to the watt-hour meter; b) the concentrator modem produces a reference signal which is synchronized with power determined by phase; c) the concentrator modem produces a request signal which is synchronized with the three-phase power determined by phase and transmits it to a watt-hour meter modem; d) the watt-hour meter modem receives the request signal; e) the watt-hour meter modem determines the phase of the power which the watt-hour meter receives according to the request signal; f) the watt-hour meter modem produces a response signal which is synchronized with the phase of the determined power and transmits it to the concentrator modem; and g) the concentrator modem receives the response signal of the watt-hour meter modem for the request signal and determines whether the response signal is synchronized with the reference signal or not and determines the phase of the power which the watt-hour meter receives.
