Analysis of Measurement Errors Caused by Incorrect Cable Disassembly and Electricity Consumption

Taking an example of a gateway electricity meter losing voltage due to accidental cable disassembly, this article analyzes the fault and explains how to calculate the incorrect electricity quantity. In order to make the results more reasonable, the station electricity balance method and the bus balance method were used for calculation, and the calculated error electricity was close, proving the correctness of the calculation method. This provides a reference and basis for the analysis and processing of similar energy metering faults and the calculation of error electricity.
