Neutral Currents The difficulty of operating three-phase star-connected generators with their neutrals in parallel, was most forcibly brought to the attention of the engineering world when the company with which I am connected attempted to operate its plants in this manner. The various phenomena of this attempt have been fully described by C. W. Ricker (Experience with a Grounded Neutral on a High-tension Plant, Electric Journal, September, 1906) and by the writer (Experience with a Grounded Neutral on the High Tension System of the Interborough Rapid Transit Company, Transactions A.I.E.E., Vol. XXVI, Part II, page 1605).
