Standards

This part of the IEC 61850 series specifies a life format for describing communication related IED (Intelligent Devices ) configurations and IED parameters, communication system configurations, switchyard (function) structure, and the relations between them. The main purpose of this format is to exchange IEC capability descriptions, and SA system descriptions between IED engineering tools and the system engineering tool(s) of different manufactures in a compatible way.

This part of the IEC 61850 series introduces the modelling methods communications principles, and information models that are used parts of IEC 61850-7 -x . The purpose of this part of the IEC 61850 series is to provide - from a conceptual point of view - assistance to understand the basic concepts and description methods for -substation -specifics information for substation automation systems.- devices functions used for substation automation purposed, and - communication systems to provide interoperability within substations.

This part of IEC 61850 specifies standard techniques for testing of conformance of implementation as well as specific measurement techniques to be applied when declaring performance parameters. The use of these techniques will enhance the ability of the system integrator to integrate IEDs easily , operate IECDs correctly , and support the applications as intended.

This international standard deals with the safety of toys that have at least one function dependent on electricity.

The present technical report covers procedures for the installation and maintenance of optical fiber cables on overhead power lines. This includes. -optical ground wire (OPGE) fiber cables. - optical phase conductor (OPPC) fiber cable. - optical attached fibre cable (OPAC) . all dielectric self supporting (ADSS) optical fiber cable - Optical fiber cables are considered for single and mullti- circuit constructions in construction in common use within some countries.

This publicly available specification covers general high - level safety requirements for all types of automated urban guided transit systems with independent self-propelled trains operating on an exclusive guideway.

This part of IEC 62271 applies to alternating current disconnectors and earthing switches designed for indoor and outdoor enclosed and open terminal installations for voltages above 1000 V and for services frequencies up to and including 60 Hz.

This part of IEC 62271 applies to all switchgear and their assemblies for alternating current of rated voltage of 72.5 kV and above for indoor and outdoor installation , including their supporting structure rigidly connected to the ground.

This international standard is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltage above 1 000 V.

This part of IEC 62271 mainly applies to a.c. circuit-beakers within the scope of IEC 62271 - 100 . It provides the general rules for testing a.c. circuit- breakers, for making and breaking capacities over the range of test duties described in 6 102 to 6. 111 of IEC 62271 -100. by synthetic methods..
