what is the frequency of ac current in north america?
60 hz
an ac voltage will cause an ac current (with an applied dc bias this is also called "ripple current"), with cyclic charging and discharging of the capacitor causing oscillating motion of the electric dipoles in the dielectric. this results in dielectric losses, which are the principal component of the esr of film capacitors, and which produce heat from the alternating current. the maximum rms alternating voltage at a given frequency which may be applied continuously to a capacitor (up to the rated temperature) is defined as the rated ac voltage u. rated ac voltages usually are specified at the mains frequency of a region (50 or 60 hz).

in sweden, norway and some areas of the former gdr three phase ac-current from the public grid is converted into single phase ac current with a frequency of 16.7 hz in substations close to the railways. in these regions there are no traction current lines.









































also in countries in which the electric trains run with direct current or with single phase ac current with the frequency of the general power grid, the required conversion of the current is performed in the substations, so that in these countries no traction current lines are needed.
