TL;DR: In this article, a number of oscillograms taken on the Liverpool Corporation electric supply system were analyzed, including current and pressure transients when hightension cables are switched on and off, with and without transformers.
Abstract: This paper records a number of oscillograms taken on the Liverpool Corporation electric supply system. These include (a) Current-rushes on switching in transformers of various ratings. (b) Current-rushes on switching in induction motorgenerators. (c) Current and pressure transients when hightension cables are switched on and off, with and without transformers. (d) Current-surges on paralleling alternators, and on synchronizing rotary converters. In order to explain the results observed on the central station records, a number of tests are included of similar phenomena observed under laboratory conditions, in which the instant of closing circuit has been controlled. The theories of the various transients are discussed, and a bibliography of papers (mostly published since 1913) is included.
