Above a certain break-even distance (about 50 km for submarine cables, and perhaps 600–800 km for overhead cables), the lower cost of the HVDC electrical conductors outweighs the cost of the electronics. Source: Internet
Although skin effect limits Tesla currents to the outer fraction of an inch in metal conductors, the ' skin depth ' of human flesh is deeper than that of a metallic conductor due to higher resistivity and lower permittivity. Source: Internet
Alternatively all components of the system such as generators, conductors, transformers, and switchgear would be increased in size (and cost) to carry the extra current. Source: Internet
Any induced noise would be present in equal amounts and in identical polarity on each of the balanced signal conductors, so the two signals’ difference from each other would be unchanged. Source: Internet
Although unlabeled, the flat bottom surfaces of the anvil and post embedded inside the epoxy act as anchors, to prevent the conductors from being forcefully pulled out via mechanical strain or vibration. Source: Internet
Also, the magnetic field of each phase conductor in a 3-phase system is negated when the other two phase conductors are nearby to form a trefoil. Source: Internet
