The roadmap describes norms and structures across DIN, CEN, ISO, DKE, CENELEC, IEC, and IEEE-related work. It also covers the economic and legal framework, including relevant directives and acts, and details protection objectives such as safety, functional safety, overcurrent, transient overvoltages, and arc-fault considerations.",{"@graph":14,"@context":71},[15,34,54],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/german-standardization-roadmap-low-voltage-dc-version-2-issue-date-june-2018/664736/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":48,"encodingFormat":47,"isAccessibleForFree":49,"interactionStatistic":50},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/german-standardization-roadmap-low-voltage-dc-version-2-issue-date-june-2018/664736.png","ImageObject",300,407,{"name":42,"@type":43},"Aria","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-29",true,{"@type":51,"interactionType":52,"userInteractionCount":22},"InteractionCounter",{"@type":53},"ViewAction",{"@type":55,"mainEntity":56},"FAQPage",[57,63,67],{"name":58,"@type":59,"acceptedAnswer":60},"What is the purpose of the Low Voltage DC German standardization roadmap version 2?","Question",{"text":61,"@type":62},"It provides a structured overview of standards, terminology, economic and legal context, and protection objectives for low-voltage direct current (LVDC).
