AB - L . V. BEWLEY Th e problems of traveling waves on the transmission lines of a power system1 differ considerably from those of traveling waves on telephone or telegraph circuits. Th e primary object in the case of the former is to know how to protect the system from abnormal voltage disturbances which might damage apparatus or cause discontinuity of service ; wherea s the object in the case of the latter is the transmis­ sion of signals. Attenuation , distortion, wave shape modification, and successive reflections are deliberately sought after on the power sys­ tem as a means of rendering the surges innocuous, but these effects mus t be carefully avoided or nullified on the communication circuits so as t o preserve the wave shape an d transmi t the signal with strength, fidelity, and without interference. On the power lines, the surges often originate from unknown causes, or at the point of origin are of un­ known magnitude and shape (except from a statistical point of view) ; while on the communication circuits the initial shape and magnitude of the wave train are known with exactness. External fields (due to charged clouds), corona, flashovers, faults, and so
