Temperature of three-conductor cables

ALTHOUGH important problems in the field of cable engineering require the determination of transient temperatures of cables, the rather formidable mathematics involved in a rigorous solution discourages many engineers from attempting these calculations. Thus, comparatively fewengineers are familiar with the methods of solving such problems. Since the ability to handle transient temperature calculations is necessary both in the determination of short-time overload ratings and in the design of oil-filled cable lines, this subject should be mastered by cable engineers employed by utility companies. A new method of solving the transient temperature and oil demand problems of 3-conductor cables is particularly stressed.
