IEC 61968-3:2021 provides utilities with the means to supervise main substation topology (breaker and switch state), feeder topology and control equipment status through SCADA, AMI and other data sources. It also provides the means for handling network connectivity and loading conditions. Finally, it makes it possible for utilities to locate customer telephone complaints and coordinate activities…

IEC 61968-3:2021 donne aux entreprises de distribution les moyens de surveiller la topologie de poste principale (état du disjoncteur et de l'organe de coupure), la topologie de lignes d'alimentation et le statut de l'équipement de commande avec SCADA, AMI et d'autres sources de données. Elle fournit également les moyens pour gérer l’état de charge et de connectivité du réseau…

IEC TS 63209-1:2021 is intended to provide information to supplement the baseline testing defined in IEC 61215, which is a qualification test with pass-fail criteria. This document provides a standardized method for evaluating longer term reliability of photovoltaic (PV) modules and for different bills of materials (BOMs) that may be used when manufacturing those modules. The included test…

IEC TS 60695-2-20:2021 describes a test method that applies to solid electrical insulating materials of which test specimens can be provided. The test measures the time required to ignite a test specimen when it is affected by heat from an electrically heated wire wound around the test specimen. If the test specimen drips, the time at which this occurs is also recorded. The test method can be…

IEC 62488-3:2021(E) applies to power line carrier terminals and networks used to transmit information over power networks including extra high, high and medium voltage (EHV/HV/MV) power lines using both digital and optionally analogue modulation systems in a frequency range between 16 kHz and 1 MHz (see also IEC 62488-1). In many countries, power line carrier (PLC) channels represent a…

This document specifies procedures and requirements for plastics, and products made from plastics, that are suitable for recovery through organic recycling. The four following aspects are addressed: a) disintegration during composting; b) ultimate aerobic biodegradation; c) no adverse effects of compost on terrestrial organisms; d) control of constituents. These four aspects are suitable to…

IEC TR 62977-1-31:2021(E) provides practical information on light measuring devices (luminance meters, colorimeters, and spectroradiometers) with luminance measuring optics for the characterization of electronic displays.
