Safety of transformers, reactors, power supply units and combinations thereof - Part 2-15: Particular requirements and tests for isolating transformers for the supply of medical locations
IEC 61558-2-15:2011 deals with safety aspects of isolating transformers for the supply of medical locations. This second edition cancels and replaces the first edition published in 1999. It constitutes a technical revision. The main changes consist of updating this part in accordance with IEC 61558-1:2005. This part has the status of a group safety publication in accordance with IEC Guide 104:2010. The preparation of safety publications and the use of basic safety publications and group safety publications. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. This publication is to be read in conjunction with IEC 61558-1:2005.

Varnost transformatorjev, dušilk, napajalnikov in njihovih kombinacij - 2-15. del: Posebne zahteve in preskusi za ločilne transformatorje v napajalnikih v medicinskih prostorih
Ta del standarda IEC 61558 obravnava varnostne vidike ločilnih transformatorjev v napajalnikih v medicinskih prostorih. Razen če ni drugače določeno, od tu naprej izraz transformator zajema ločilne transformatorje v napajalnikih v medicinskih prostorih. Ta del velja za stacionarne, enofazne ali trifazne, zračno hlajene (naravno ali umetno) samostojne suhe ločilne transformatorje v napajalnikih v medicinskih sistemih IT za medicinske lokacije iz skupine 2, ki so stalno povezani s fiksnim ožičenjem ter so del napajalnega sistema IT na sekundarni strani. Navitja so lahko enkapsulirana ali neenkapsulirana. Nazivna napajalna napetost ne presega 1000 V izmenične napetosti. Nazivna napajalna frekvenca in notranja operativna frekvenca ne presegata 500 Hz. Nazivna izhodna moč ni manjša od 0,5 kVA in ne presega 10 kVA za enofazne in trifazne transformatorje. Ta del velja za transformatorje brez omejitev nazivne izhodne moči, o čemer se dogovorita kupec in izdelovalec. Izhodna napetost brez obremenitve in nazivna (izhodna) izmenična napetost ne presegata 250 V izmenične napetosti za enofazne ali trifazne transformatorje (medfazna napetost). Ta standard ne zajema enote električnega napajalnika. Ta del ne velja za zunanje tokokroge in njihove sestavne dele, ki so namenjeni za povezavo z vhodnimi in izhodnimi terminali transformatorjev. Transformatorji, ki jih ta del obravnava, se uporabljajo v aplikacijah, v katerih pravila inštalacij ali specifikacije aplikacije zahtevajo dvojno ali ojačano izolacijo med tokokrogi. – Za transformatorje, ki so namenjeni za uporabo v vozilih, na ladjah in letalih, so morda potrebne dodatne zahteve (iz drugih veljavnih standardov, nacionalnih pravil itd.); – upoštevati je treba tudi ukrepe za zaščito ohišja in sestavnih delov v ohišju pred zunanjimi vplivi, kot so glive, mrčes, termiti, sončno sevanje in zmrzovanje; – upoštevati je treba tudi različne pogoje za transport, shranjevanje in delovanje transformatorjev; – za transformatorje, ki so namenjeni za uporabo v posebnih okoljih, lahko veljajo dodatne zahteve v skladu z drugimi ustreznimi standardi in nacionalnimi pravili.

Part 2-15: Particular requirements and tests
for isolating transformers for the supply of medical locations
FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users
