1. A method of detecting theft of electrical energy, the method 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.
