“…A few months later, Atkinson [17] presented a continuation of his previous work [13], where he determined the dielectric stresses and the geometric factor in three-conductor cables from new measurements performed on immersed electrodes and showed satisfactory agreement with the results obtained from Simons' graphical method [14]. To further extend the previous publication [15], Melsom and Beer [18] reported new results of measurements carried out on single-phase cable systems laid up straight on a wooden floor, surrounded by still air.…”
