Measurements of voltage and current over a long artificial power-transmission line at 25 and 60 cycles per second

It is the purpose of this paper to describe in detail a series of measurements of voltage and current over an artificial power-transmission line 1040 km. (646.2 miles) in length. Although it is readily possible to compute the behavior of such a length of line, when the linear constants are given; yet this is the first time, so far as the writers are aware, that actual observations have been forthcoming on a laboratory model power-transmission line of more than about 200 km. (130 miles) in length.¹
