Selliste seadmete hulka kuuluvad galvaanielementide ja akumulaatorite patareid, muud vahelduv- või alalisvoolu toiteallikad, elektriseadmed (kaasa arvatud tööstus- ja sideseadmed) ja elektritarvitid. See standard ei kehti signaale või mõõteväärtusi esitavatele või neid edastavatele pingetele. See standard ei kehti elektriseadmete sees või elektriseadmestiku üksikelementides kasutatavate komponentide ja üksikosade standardpingetele.

See standard määratleb nende standardpingete väärtused, mis on ette nähtud - elektrivarustussüsteemide nimipingete eelisväärtusteks, ja - seadmestiku ja võrgu projekteerimise normväärtusteks. MÄRKUS 1 Kaks peamist põhjust, mis peavad juhtima selles standardis määratletud väärtusteni, on: Selles standardis määratletud nimipingete (või seadme suurimate kestevpingete) väärtused põhinevad peamiselt elektrivarustussüsteemide ajaloolisel arengul kogu maailmas, kuna need väärtused on osutunud enim levinenuteks ja on leidnud ülemaailmse tunnustuse; Selles standardis mainitud pingepiirkonnad on leidnud tunnustamist kõige sobivama alusena elektriseadmete ja –süsteemide projekteerimisel. MÄRKUS 2 Sellele vaatamata jääb sobivate katseväärtuste, katsetingimuste ja heakskiidu kriteeriumite määramine süsteemi ja tootestandardite ülesandeks.
This publication applies to– a.c. transmission, distribution and utilization systems and equipment for use in such systems with standard frequencies 50 Hz and 60 Hz having a nominal voltage above 100 V; – a.c. and d.c. traction systems; – a.c. and d.c. equipment having nominal voltages below 120 V a.c. or below 750 V d.c., the a.c. voltages being intended (but not exclusively) for 50 Hz and 60 Hz applications; such equipment covers batteries (from primary or secondary cells), other power supply devices (a.c. or d.c.), electrical equipment (including industrial and communication), and appliances. This publication does not apply to voltages representing or transmitting signals or measured values. This publication does not apply to standard voltages of components and parts used within electrical devices or items of equipment. This publication specifies standard voltage values which are intended to serve − as preferential values for the nominal voltage of electrical supply systems, and − as reference values for equipment and system design. NOTE 1 Two main reasons have led to the values specified in this standard: The values of nominal voltage (or highest voltage for equipment) specified in this standard are mainly based on the historical development of electrical supply systems throughout the world, since these values turned out to be the most common ones, and have achieved worldwide recognition; The voltage ranges mentioned in this standard have been recognized to be the most appropriate ones as a basis for design and testing of electrical equipment and systems. NOTE 2 It is nevertheless the task of system and product standards to define appropriate testing values, testing conditions and acceptance criteria.

This International Standard deals with the techniques for sampling free gases from gascollecting relays from power transformers. Three methods of sampling free gases are described. The techniques for sampling oil from oil-filled equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors is described in IEC 60475, section 4.2. Before analyzing the gases dissolved in oil, they must first be extracted from the oil. Three basic methods are described, one using extraction by vacuum (Toepler and partial degassing), another by displacement of the dissolved gases by bubbling the carrier gas through the oil sample (stripping), and the last one by partition of gases between the oil sample and a small volume of the carrier gas (headspace). The gases are analyzed quantitatively after extraction by gas chromatography; a method of analysis is described. Free gases from gas-collecting relays are analyzed without preliminary treatment. The preferred method for assuring the performance of the gas extraction and analysis equipment, considered together as a single system, is to degas samples of oil prepared in the laboratory and containing known concentrations of gases (“gas-in-oil standards”) and quantitatively analyze the gases extracted. Two methods of preparing gas-in-oil standards are described. For daily calibration checks of the chromatograph, it is convenient to use a standard gas mixture containing a suitable known amount of each of the gas components to be in a similar ratio to the commons ratios of the gases extracted from transformer oils. The techniques described take account, on the one hand, of the problems peculiar to analyses associated with acceptance testing in the factory, where gas contents of oil are generally very low and, on the other hand, of the problems imposed by monitoring equipment in the field, where transport of samples may be by un-pressurized air freight and where considerable differences in ambient temperature may exist between the plant and the examining laboratory.

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
This part of IEC 61558 deals with safety aspects of isolating transformers for the supply of medical locations. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the term transformer covers isolating transformers for the supply of medical locations. This Part 2-15 is applicable to stationary, single-phase or three-phase, air-cooled (natural or forced) independent dry-type isolating transformers for the supply of medical IT systems for group 2 medical locations, designed to be permanently connected to the fixed wiring and intended to form the IT power system on the secondary side. The windings may be encapsulated or non-encapsulated. NOTE 2 IT power systems are defined in IEC 60364-1. NOTE 3 The installation rules for medical IT systems for group 2 medical locations are covered by IEC 60364-7-710. NOTE 4 Transformers covered by this standard are intended for the supply of medical locations. All other transformers or equipments connected downstream from the transformer are not covered by this Part 2 (transformers for medical appliance, transformers to supply medical lamps, etc.) The rated supply voltage does not exceed 1 000 V a.c. The rated supply frequency and internal operational frequency does not exceed 500 Hz. The rated output does not be less than 0,5 kVA and does not exceed 10 kVA for single-phase and three-phase transformers. This Part 2-15 is applicable to transformers without limitation of the rated output subject toan agreement between the purchaser and the manufacturer. NOTE 5 Transformers intended to supply power to distribution networks are not covered by this Standard. The no-load output voltage and the rated output voltage do not exceed 250 V a.c. for single-phase or three-phase transformer (phase-to-phase voltage). This standard does not cover power supply unit. This Part 2-15 is not applicable to external circuits and their components intended to be connected to the input terminals and output terminals of the transformers. Transformers covered by this Part 2-15 are used in applications where double or reinforced insulation between circuits is required by the installation rules or by the appliance specification.
