Schematic representation of measurement categories. Measurement category is a method of classification by the International Electrotechnical Commission (IEC) [1] of live electric circuits used in measurement and testing of installations and equipment, usually in the relation within a building (residential or industrial).
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 ...
CIM and Substation Configuration Language (SCL) are developed in parallel under different IEC TC 57 working groups. Though both have the ability to exchange model and configuration information between different equipment or tools and use XML for storage, many differences separate the standards: CIM is based on UML, using inheritance.
An electrical code is a term for a set of regulations for the design and installation of electrical wiring in a building. The intention of such regulations is to provide standards to ensure electrical wiring systems are safe for people and property, protecting them from electrical shock and fire hazards.
