Method and apparatus for determining the location of an arc in a waveguide transmission line or the like

摘要

A method and circuit for locating an arc in a waveguide which utilize detectors responsive to the vibratory and electromagnetic disturbances resulting from an arc. Since the disturbances travel at different velocities, the location of the arc can be readily determined. A counter counts time periods between the time of detection of the electromagnetic disturbance and the time of detection of the vibratory disturbance. The length of the time periods is selected so that the quantity counted may be directly displayed as the distance to the arc location.
