The 16 Divisions of construction, as defined by the Construction Specifications Institute (CSI)'s MasterFormat, is the most widely used standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. and Canada.
The WIPS server correlates the information, validates it against the defined policies, and classifies if it is a threat. The administrator of the WIPS is then notified of the threat, or, if a policy has been set accordingly, the WIPS takes automatic protection measures. WIPS is configured as either a network implementation or a hosted ...
It aims to allow application software to exchange information about an electrical network. [1] It has been officially adopted by the International Electrotechnical Commission (IEC). The CIM is currently maintained as a UML model. [2] It defines a common vocabulary and basic ontology. CIM models the network itself using the 'wires model'.
IEC 62141 Helical-scan digital video cassette recording format using 12,65 mm magnetic tape and incorporating MPEG-4 compression – Type D-16 format; IEC TS 62143 Electrical installations for lighting and beaconing of aerodromes – Aeronautical ground lighting systems – Guidelines for the development of a safety lifecycle methodology
A form of energy transfer between two physically close tuned circuits. return loss A measure of the power loss due to a signal reflection by a discontinuity in a transmission line or an optical fiber. RF connector An electrical fitting used to connect cables carrying radio frequency currents. RF engineering
COMTRADE files are typically generated by Intelligent Electronic Devices , such as an electronic protective relay, in electrical substations during power systems disturbances. These IEDs monitor the electrical characteristics of the power system by digitally sampling measurements of the current, voltage, power, frequency, etc. at a high speed.
By 1914, the IEC had issued a first list of terms and definitions covering electrical machinery and apparatus, a list of international letter symbols for quantities and signs for names of units, a list of definitions in connection with hydraulic turbines, and a number of definitions and recommendations relating to rotating machines and ...
The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic assemblies. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays. Industrial electrical installations often use reference designators according to IEC 81346.
