The capacitor — An aid to electric-power service for pipe lines

IN the over-all design of an electrified oil pipe line, power service constitutes a major problem, not only because of its importance in the economic structure, but also because it is a problem more varied in its component parts than almost any other phase of the project. Station designs are for the most part repetitive; power-service facilities, up to the point of delivery, vary widely from station to station. In the completion of three recent major pipe-line projects, power service has been facilitated in numerous instances by capacitors; in some cases, under conditions imposed by wartime conservation of power-service materials, capacitors have been the key to successful station operation.
