IEC 60076-22-1:2019 applies to protective devices mounted on liquid-immersed power transformers in accordance with IEC 60076-1 and reactors in accordance with IEC 60076-6 with or without conservator for indoor or outdoor installation. It outlines the service conditions and the mechanical and electrical requirements that are common to all the devices, which are relevant for the safety of the…

IEC 60076-22-1:2019 s'applique aux dispositifs de protection installés sur des transformateurs de puissance immergés dans un liquide conformes à l'IEC 60076-1 et aux bobines d'inductance conformes à l'IEC 60076-6 avec ou sans conservateur, pour les installations intérieures ou extérieures. Elle présente les conditions de service et les exigences mécaniques et électriques…

IEC TS 60904-1-2:2019 describes procedures for the measurement of the current-voltage (I-V) characteristics of bifacial photovoltaic devices in natural or simulated sunlight. It is applicable to single PV cells, sub-assemblies of such cells or entire PV modules. This document may be applicable to PV devices designed for use under concentrated irradiation if they are measured without the optics…

This document specifies additional competence requirements for personnel involved in the audit and certification process of a management system for sustainable development in communities and complements the existing requirements of ISO/IEC 17021‑1.

This document specifies the Open Font Format (OFF) specification, including the TrueType and Compact Font Format (CFF) outline formats. Many references to both TrueType and PostScript exist throughout this document, as Open Font Format fonts combine the two technologies. The document defines data structures for variaous font tables, and provides the necessary details for developers to build a…

IEC 62747:2014+A1:2019 defines terms for the subject of self-commutated voltage-sourced converters used for transmission of power by high voltage direct current (HVDC). The standard is written mainly for the case of application of insulated gate bipolar transistors (IGBTs) in voltage sourced converters (VSC) but may also be used for guidance in the event that other types of semiconductor devices…
