The neutral-to-earth voltage (NEV) test case and distribution system analysis

Modeling NEV issues requires the most detailed circuit models for distribution system analysis except for, perhaps, lightning surge protection analysis. A proposed line model benchmark is solved and results reported. Modeling NEV will become an increasingly important problem. Based on the proliferation of harmonic producing loads in residential environments, the amount of triplen harmonics will tend to increase, with an accompanying increase in neutral-earth voltages.
