C<\/span>ontain\u00ader ships and cruise lin\u00aders demand some\u00adwhere in the range of 3 to 16 megawatts of elec\u00adtric\u00adi\u00adty. That is eas\u00adi\u00adly enough for a small town. In most of the world\u2019s ports, the diesel engines even run when the ship is at anchor, since the crew, guests and, of course, the equip\u00adment still need elec\u00adtric\u00adi\u00adty. This puts a major strain on port cities, how\u00adev\u00ader, because the air qual\u00adi\u00adty suf\u00adfers great\u00adly from the exhaust fumes.

\nThere\u00adfore, the ports of Ham\u00adburg and Kiel (pic\u00adtured) are among the first in the world that are turn\u00ading to shore pow\u00ader sup\u00adply. But it is not enough to plug the ship in and turn the diesel engine off. Ship and shore pow\u00ader grids use dif\u00adfer\u00adent volt\u00adages and fre\u00adquen\u00adcies. There\u00adfore, fre\u00adquen\u00adcy con\u00advert\u00aders and match\u00ading trans\u00adform\u00aders are nec\u00ades\u00adsary. Active and pas\u00adsive GRIDCON\u00ae har\u00admon\u00adic fil\u00adters from Rein\u00adhausen are used to ensure that there is no imper\u00admis\u00adsi\u00adble grid feed\u00adback into pub\u00adlic dis\u00adtri\u00adb\u00adu\u00adtion grids via the grid con\u00adnec\u00adtion. They keep the shore grid clean, while indi\u00adrect\u00adly keep\u00ading the air clean as well.<\/p>\n
