Representing all faults in an electricity meter by an overall health value

摘要

Disclosed is a metering system (100). The metering system (100) comprises a meter base which includes a meter bus connectable between an electrical source (102) and an electrical load (107). The metering system (100) further comprises sensors (104, 106) configured to determine electrical characteristics of electrical power in the meter bus and a processor (114). The processor (114) is configured to receive outputs of the sensors (104, 106) which are used to determine revenue parameters for the metering system (100) and at least one fault associated with the operation of the metering system (100). The determination of at least one fault is further based on the determination of revenue parameters and a processing fault generated by the processor (114). The processor (114) further determines a severity level of each fault and determines a single value indicating the health of the meter (100) using the determined at least one fault and uses this single health value to determine a course of action for returning the meter (100) to service.
