Electrical energy loss detection

A system, comprising:

• one or more processors configured to:
• measure, for each time sample of a number of time samples, a neutral current of an electrical energy metering system;
• sum, for each time sample of the number of time samples, a number of measured phase current values of the electrical energy metering system to determine an imputed neutral current;
• determine, for each time sample of the number of time samples, a squared difference between the measured neutral current and the imputed neutral current;
• integrate, for each time sample of the number of time samples, the squared difference to determine an accumulator value;
• and
• detect, based on the accumulator value, theft of electrical energy from the electrical energy metering system.

A non-transitory computer-readable medium having computer instructions stored thereon that are executable by a processing device to perform or control performance of operations comprising:

• measuring, for each time sample of a number of time samples, a neutral current of an electrical energy metering system;
• summing, for each time sample of the number of time samples, a number of measured phase current values of the electrical energy metering system to determine an imputed neutral current;
• determining, for each time sample of the number of time samples, a squared difference between the measured neutral current and the imputed neutral current;
• integrating, for each time sample of the number of time samples, the squared difference to determine an accumulator value;
• and
• detecting, based on the accumulator value, theft of electrical energy from the electrical energy metering system.
