Experimental and Theoretical Analysis of Wrong Wiring of Three-phase Three-wire Watt-hour Meters
Wrong wiring of electric energy meters is a common problem in the application of electricity meters which seri-ously affected the economic interests of both power suppliers and consumers.Studying the wrong wiring mode of electric energy meters is of great significance for fault analysis and electric energy accounting.Taking the three-phase three-wire watt-hour meter as the research object,the watt-hour meter wrong wiring experiment was carried out in this paper by constructing the test platform for watt-hour meter wiring,and the characteristics of the electrical signal displayed by the watt-hour meter under the condition of three-phase three-wire watt-hour meter wrong wiring operation were studied and analyzed by constructing the wrong wiring power check table and conducting the wrong wiring control group experiment.
