SIST EN 61869-3 : 2012
NACIONALNI UVOD
Standard SIST EN 61869-3 (sl), Instrumentni transformatorji – 3. del: Posebne zahteve za induktivne
napetostne transformatorje, 2012, ima status slovenskega standarda in je istoveten evropskemu
standardu EN 61869-3 (en), Instrument transformers – Part 3: Specific requirements for inductive
voltage transformers, 2011.
Ta standard nadomešča SIST EN 60044-2:2001, SIST EN 60044-2:2001/A1:2001 in SIST EN 60044-
2:2001/A2:2003.
NACIONALNI PREDGOVOR
Mednarodni standard IEC 61869-3:2011 je pripravil tehnični odbor Mednarodne elektrotehniške komisije
IEC/TC 38 Instrumentni transformatorji, potrdil pa tehnični odbor Evropskega komiteja za
standardizacijo v elektrotehniki CLC/TC 38X Instrumentni transformatorji. Slovenski standard SIST EN
61869-3:2012 je prevod evropskega standarda EN 61869-3:2011. V primeru spora glede besedila
slovenskega prevoda v tem standardu je odločilen izvirni evropski standard v angleškem jeziku.
Slovensko izdajo standarda je potrdil Strokovni svet SIST za področja elektrotehnike, informacijske
tehnologije in telekomunikacij.

Odločitev za privzem tega standarda je v januarju 2012 sprejel Strokovni svet SIST za področja
elektrotehnike, informacijske tehnologije in telekomunikacij.

ZVEZA Z NACIONALNIMI STANDARDI

S privzemom tega evropskega standarda veljajo za omejeni namen referenčnih standardov vsi
standardi, navedeni v izvirniku, razen tistih, ki so že sprejeti v nacionalno standardizacijo:
