Abstract :
To the Editor of the Journal: In the paper on Electrification of Oil Pipe Lines in the Southwest, by D. H. Levy, published in the Journal of the A. 1. E. E., June 1929, p. 434, it is stated that squirrelcage induction motors are used for driving the centrifugal pumps in all cases, and that if there were a power-factor penalty the use of static condensers would be justified in most cases.
