| Zusammenfassung: | The invention discloses an adaptive control method for a three-phase electric energy meter, and a three-phase electric energy meter. The adaptive control method for the three-phase electric energy meter comprises the following steps: the access way of the three-phase electric energy meter is confirmed by determining the range of the accessed three-phase inter-phase voltage angle and three-phase voltage value; and the corresponding processing program and metering mode are called by the access way of the three-phase electric energy meter, so that a three-phase electric energy meter automatically adapts to an access environment of three-phase four-wire 3*57.7/100V, three-phase four-wire 3*220/380V or three-phase three-wire 3*100V; the product specification of the electrical energy meter is reduced, and the production and management difficulties are greatly lowered for production enterprises and users. |
