The calculation and elimination of undesirable electromagnetic field influence on cranes

Electromagnetic (EM) fields in the surroundings of powerful transmitting antennas, energetic installations and machines induce currents and voltages on some conductive constructions that exist or are temporarily carried into these fields and thus endanger human life and working environment. The graphics of effective values of touch voltages and short-cut currents induced on the tongs of the loads for some examples of cranes in external homogenous EM field of elliptically polarized plane wave, concerning ground as perfectly conductive, are presented in this paper.
