18. An intelligent electronic device, comprising:
processing circuitry;
a communication system; and
a memory device comprising instructions that cause the processing circuitry to:
calculate a power phasor for each phase of a multi-phase capacitor bank system with respect to an ABC phase rotation, an ACB phase rotation, or both, wherein the power phasor comprises a vector product of a voltage received from a respective combo sensor at each phase of one or more phases of the multi-phase capacitor bank system and a fundamental frequency of a neutral current received from a neutral current sensor;
in response to each magnitude of each power phasor being greater than a threshold value:
determine which of the one or more phases are open based on each phase angle of each power phasor; and
issue a notification indicating the one or more phases that are open.
