A surge counter for transmission lines

A consideration of several methods which have previously been used in the investigation of surge phenomena leads to a review of some of the design requirements for the instrument described in the paper, which includes a simplification of design by the use of Post-Office-type counters. The design of this surge counter is then considered in detail, and its operation explained, in conjunction with block and circuit diagrams:a diagram of a recording obtained automatically by the instrument is shown.
