Abstract :
TO DETERMINE past and present practice for generator leads, a questionnaire was sent to utility and engineering companies requesting a description of the design and material used for each of their installations and their basic reasons for the type of installation chosen. They also were requested to cite any operating failures or difficulties and state whether the same design would be used again and, if not, why not. To avoid attempting to cover too much ground, the questionnaire was confined to generators having a rating of 20,000 kw or larger, installed in the past 10 years, or now being installed.
