Discussion on “the influence of frequency of alternating or infrequently-reversed current on electrolytic corrosion” (Mccollum-Ahlborn), New York, March 10, 1916 (see proceedings for March, 1916)

Philip Torchio: The most important results in the findings in these investigations are, first, that with ordinary frequencies of 25 to 60 cycles, the corrosion of underground structures is, practically nil. In this country some of the water companies are still objecting to having the electric lighting companies ground their neutrals to the pipes of the water companies. I think that the results of the investigation of the Bureau of Standards should dissipate any fear of trouble due to the grounding of neutrals to the water pipes.
