Terminology for voltage-sourced converters (VSC) for high-voltage direct current (HVDC) systems
IEC 62747:2014 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 which…
Telecontrol equipment and systems - Part 6-702: Telecontrol protocols compatible with ISO standards ...
IEC 60870-6-702:2014 is a functional profile (FP) and defines the provision of the TASE.2 communications services between two control centre end systems. It is supported by the transport services implemented in accordance with transport-profiles defined for the type of network that interconnects the control centre end systems. The main changes with respect to the previous edition are listed below…
IEC/IEEE 65700-19-03:2014 applies to outdoor and indoor bushings of any voltage used on DC systems, of capacitance graded or gas insulated types for use as components of oil-filled converter transformers and smoothing reactors, as well as air-to-air DC bushings. This standard makes reference to IEC 60137 for general terms and conditions and defines the special terms used, operating conditions,…
Radiation protection instrumentation - Radon and radon decay product measuring instruments - Part 2:...
IEC 61577-2:2014 describes the specific requirements for instruments measuring the activity concentration of airborne 222Rn and 220Rn outdoors, in dwellings and in workplaces including underground mines. This standard applies practically to all types of electronic measuring instruments that are based on either spot or continuous measurements. The different types of instrumentation used for…
