| Abstract: | This paper describes a fault＇s treatment process which is caused by the inconsistency of general three-phase electric energy meter and the memory. The register reading of a certain electric energy meter is different from that of the load control system. Through on-site inspection and experimental simulation analysis, the fault reason is found： the energy is not calculated in the memory when RS485 port is in the reverse situation. The fault electric energy meters are repaired and replaced, the economic losses are avoided and some suggestions are put forward to avoid the similar failures. |
