💡 Standard Snapshot: IEC 62368-3 (Edition 1.0, 2017) addresses the safety aspects of DC power transfer through communication cables in audio/video, information and communication technology (ICT) equipment. It is part of the IEC 62368 series which has replaced IEC 60950…
Standardized framework for assessing electromagnetic field exposure from EAS, RFID, and similar short range devices — covering measurement, modelling, and compliance evaluation Introduction to EMF Exposure Evaluation for Short Range Devices Short range devices (SRDs) such as electronic article surveillance…
💡 Standard Snapshot: IEC 62364 (Edition 1.0, 2013) provides a comprehensive guide for dealing with hydro-abrasive erosion in Kaplan, Francis, and Pelton turbines. It covers erosion mechanisms, prediction methodologies, material selection, design considerations, and maintenance strategies for hydropower plants operating…
💡 Standard Snapshot: IEC 62365 (Edition 2.0, 2009) specifies the method for transmitting digital audio signals over Asynchronous Transfer Mode (ATM) networks. It defines how to pack digital audio samples into ATM cells, establish switched virtual circuits for audio connections,…
💡 Standard Snapshot: IEC 62366-1 (Edition 1.0, 2015, with Corrigendum 1:2016) specifies the usability engineering process for medical devices. It establishes a framework for analyzing, designing, testing, and validating the user interface of medical devices to minimize use errors and…
Ferrite cores are manufactured through a powder metallurgy process involving pressing and sintering at temperatures above 1200°C. Despite advances in process control, the manufacturing process inevitably produces cores with minor surface irregularities—chips, cracks, flash, and porosity. The critical engineering question…
The smart grid vision promises seamless data exchange between utility control centers, substations, field devices, and market participants. Yet the reality is that two fundamentally different information models govern these domains: the Common Information Model (CIM), used in energy management…
When a power electronics engineer specifies a ferrite core for a transformer or inductor design, the choice involves far more than just the core shape and size. The engineer must define material grade, initial permeability, saturation flux density, core loss…
💡 Standard Snapshot: IEC 62363 (Edition 1.0, 2008) specifies requirements for portable photon contamination meters and monitors used for detecting and measuring surface contamination from gamma-emitting and X-ray-emitting radionuclides. It covers instruments used in nuclear facilities, medical settings, and radiation…
Modern power grids are among the most complex cyber-physical systems ever built. They integrate generation plants spanning megawatts to kilowatts, transmission networks crossing continents, distribution grids reaching individual homes, and an ever-growing fleet of distributed energy resources (DERs). Each subsystem…
