The ener\u00adgy land\u00adscape in the USA is as diverse as the coun\u00adtry itself. In par\u00adtic\u00adu\u00adlar, the dis\u00adtri\u00adb\u00adu\u00adtion net\u00adworks reflect many of the geo\u00adgraph\u00adi\u00adcal con\u00adtrasts. Thou\u00adsands of oper\u00ada\u00adtors sup\u00adply end users with electricity\u2014from sprawl\u00ading rur\u00adal areas with tra\u00addi\u00adtion\u00adal infra\u00adstruc\u00adture, to urban metrop\u00ado\u00adlis\u00ades with high indus\u00adtri\u00adal den\u00adsi\u00adty and smart grid infra\u00adstruc\u00adtures. <\/p>\n\n\n\n

Com\u00adpared to Euro\u00adpean grids, a spe\u00adcial fea\u00adture of US dis\u00adtri\u00adb\u00adu\u00adtion net\u00adworks is that the low-volt\u00adage net\u00adworks are most\u00adly 120V single-phase\u2014an archi\u00adtec\u00adture that has proven par\u00adtic\u00adu\u00adlar\u00adly effec\u00adtive for sup\u00adply\u00ading the often sprawl\u00ading res\u00adi\u00adden\u00adtial areas. The advan\u00adtages are obvi\u00adous where con\u00adsumers are spread over a large area: Sin\u00adgle-phase sys\u00adtems are sim\u00adpler to install, require few\u00ader oper\u00adat\u00ading resources, and thus low\u00ader invest\u00adment out\u00adlays. How\u00adev\u00ader, per\u00adfor\u00admance is also more lim\u00adit\u00aded com\u00adpared to three-phase sys\u00adtems, and volt\u00adage fluc\u00adtu\u00ada\u00adtions and imbal\u00adances occur more eas\u00adi\u00adly if loads are not even\u00adly dis\u00adtrib\u00aduted across the phase.<\/p>\n\n\n\n

It offers a wide con\u00adtrol range and is main\u00adte\u00adnance-free. It makes pos\u00adsi\u00adble the use of VRDTs in the US mar\u00adket which offer crit\u00adi\u00adcal ben\u00ade\u00adfits to util\u00adi\u00adties such as mul\u00adti\u00adply\u00ading net\u00adwork absorp\u00adtion capac\u00adi\u00adty, sup\u00adport\u00ading ener\u00adgy effi\u00adcien\u00adcy pro\u00adgrams, and elim\u00adi\u00adnat\u00ading cost\u00adly rewiring.<\/p>\n<\/div><\/div>\n\n\n\n

And this is pre\u00adcise\u00adly where Reinhausen\u2019s role in the USA becomes cru\u00adcial. With our ECOTAP\u00ae VPD\u00ae I on-load tap-chang\u00ader for sin\u00adgle-phase dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders, VRDTs become a viable option. Con\u00adse\u00adquent\u00adly, we are able to resolve the major\u00adi\u00adty of issues for dis\u00adtri\u00adb\u00adu\u00adtion sys\u00adtem oper\u00ada\u00adtors, enabling them to regain con\u00adtrol over their volt\u00adage band.\u201d The three exam\u00adples at left show how Rein\u00adhausen solves the prob\u00adlems of region\u00adal US util\u00adi\u00adties with VRDTs.\u2002<\/p>\n\n\n\n

Thou\u00adsands of oper\u00ada\u00adtors sup\u00adply end con\u00adsumers with elec\u00adtric\u00adi\u00adty. Because the low-volt\u00adage grid in the USA is most\u00adly sin\u00adgle-phase, Rein\u00adhausen has devel\u00adoped a tap-chang\u00ader that can be used to imple\u00adment VRDT. The first util\u00adi\u00adties are already ben\u00ade\u00adfit\u00ading from high\u00ader grid con\u00adsump\u00adtion capac\u00adi\u00adties and a more sta\u00adble volt\u00adage band.<\/p>\n\n\n\n
