dc.description.abstract	A high percentage of large, high-speed compressor trains has suffered serious failures which were initiated by shaft current damage. These currents are generated by electromagnetic effects. The basic mechanics of various types of shaft currents arc briefly reviewed, and the electromagnetic type is discussed in detail. Part I covers the theory of current generation, sources of magnetism, symptoms, modes of failure, remedial action, and case histories. Part II explains in more detail how small residual magnetic fields can generate currents, and how self-excitation and consequent self-magnetization may occur. Principles of demagnetization are also covered.	en
