Podaljšano prehodno obdobje za prilagoditev nazivne napetosti v elektroenergetskih omrežjihMatvoz, DejanLeta 1983 je IEC sprejel standard IEC 60038, v katerem je standardiziral napetosti na vseh napetostnih nivojih v elektroenergetskih omrežjih. V standardu je določeno, da je standardna napetost na ... nizkonapetostnem nivoju v trivodnih in štirivodnih trifaznih sistemih 230 V med linijskim (faznim) in nevtralnim vodnikom oziroma 400 V med linijskimi (faznimi) vodniki. Potrebo pri poenotenju nazivne napetosti - do tedaj je bila namreč v kontinentalnem delu Evrope nazivna napetost 220 V, v Veliki Britaniji pa 240 V - je podprlo predvsem prizadevanje po znižanju stroškov proizvodnje električnih naprav in po poenotenju trga. Da bi bil prehod na novo napetost čim mehkejši, standard navaja tudi prehodno obdobje največ 20 let (od leta 2003), v katerem naj bi v najkrajšem možnem času v kontinentalnem delu Evrope prešli v prvi fazi na napetost 230 V + 6%/-10% in v Veliki Britaniji na 230 V +10%/-6%. Po preteku prehodnega obdobja (konec leta 2003) pa naj bi bila standardizirana napetost 230 V+-10%.Source: ER : elektrotehnika za praktično rabo. - ISSN 1580-3589 (Št. 2, 2004, str. 18)Type of material - article, component partPublish date - 2004Language - slovenianCOBISS.SI-ID - 26576133
