Method and system for indicating faults in an electricity meter

A method of determining a health of a metering system, said method comprising:

• receiving indication of a plurality of faults of a plurality of possible fault types, wherein the plurality of possible fault types include error faults and caution faults, the error faults include critical and non-critical severity levels, the caution faults include high, medium, and low severity levels;
• determining a number of the plurality of faults respective of a total number of the plurality of possible fault types supported by the metering system;
• weighting the severity of each of the plurality of faults using the determined number and the plurality of possible fault types;
• and
• determining a single value for a health of the metering system using the received indication, the determined number, and the weighted severity.

A computer program embodied on a non-transitory computer-readable medium, said computer program comprising at least one code segment that configures a processor to:

• receive outputs from a plurality of sensors;
• determine revenue parameters for an energy metering system using the received outputs;
• determine a plurality of faults of a plurality of possible fault types associated with the operation of the energy metering system using the received outputs, the determination of the revenue parameters, and a processing fault generated by the processor;
• determine a type of fault for each of the plurality of faults, wherein each type of fault includes a severity level;
• and
• determine a single value for a health of the energy metering system using at least the severity level of each type of fault of the plurality of faults.
