Electricity is the engine of technological progress, standards are the engine of progress for business
Since the invention of electricity, its use has become key in matters not only of production, but also of human lives in principle. Of course, the scope of this term has gone far from its initial perception and gained global proportions. That is why international standards have emerged in the application of new technologies. Since time does not stand still and each country contributes to world development, the concept of technology is also regulated at the international level. The list of these standards will give you an opportunity to assess the significance of their application to improve your business.
Low-voltage switchgear and controlgear assemblies - Part 7: Assemblies for specific applications such as marinas, camping sites, market squares, electric vehicle charging stations
Variations in electrical appliances and their applications are giving rise to an increasing number of international standards. One of the key in this area is IEC 61439-7: 2018.
This document defines the specific requirements of assemblies as follows:
– assemblies intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment;
– assemblies operated by ordinary persons (e.g. plug and unplug of electrical equipment);
– assemblies intended to be installed and used in market squares, marinas, campsites and other similar outdoor public sites;
– assemblies intended for charging stations for electric vehicles (AEVCS) for Mode 3 and Mode 4.
They are designed to integrate the functionality and additional requirements for electric vehicle conductive charging systems according to IEC 61851-1:2017. This first edition cancels and replaces the relevant technical specification published in 2014. It constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous technical specification: a new classification of the stationary ASSEMBLIES in accordance with their mechanical resistance (5.702); a new Table 702 with the list of tests and relevant severities to which the ASSEMBLIES have to be subjected according to the classification mentioned at point a); a new Annex (CC) with a new endurance test for the individual switching devices intended to be used in AEVSC, if they have not already been tested against this requirement; a general editorial review and a technical revision. The contents of the corrigendum of August 2019 have been included in this copy.
Since each area has a large number of standards that are updated annually, we recommend that you familiarize yourself in more detail with various documents from your area of activity for a clearer understanding of which regulatory act will be most suitable for further development.
Low-voltage switchgear and controlgear - Electromagnetic compatibility assessment for switchgear and controlgear and their assemblies (IEC/TR 63216:2019)
Continuing the topic of standards that can be applied in everyday life, even if they relate to electrical technologies, such a standard as SIST-TP CLC IEC / TR 63216: 2020 should be noted. The purpose of this document is to define homogeneous categories for the electromagnetic environments in order to harmonize as far as practicable all general rules and product standard requirements of electromagnetic compatibility (EMC), applicable to low-voltage switchgear, controlgear and their assemblies with built-in electronic circuits.
Since this document characterizes mainly the global characteristics of these technologies, if you are interested in this document, we recommend that you familiarize yourself with the technical details on our website in more detail.

Energy management system application program interface (EMS-API) - Part 301: Common information model (CIM) base
Energy management makes it possible to optimize the resources used and increase the productivity of the activities carried out. In order to understand clear software norms for the implementation of this activity, it is necessary to follow the guidelines in international standards such as IEC 61970-301: 2020.
This document (E) lays down the common information model (CIM), which is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of network applications developed independently by different vendors, between entire systems running network applications developed independently, or between a system running network applications and other systems concerned with different aspects of power system operations, such as generation or distribution management. SCADA is modeled to the extent necessary to support power system simulation and inter-control centre communication.
The CIM facilitates integration by defining a common language (i.e. semantics) based on the CIM to enable these applications or systems to access public data and exchange information independent of how such information is represented internally. This edition reflects the model content version ‘IEC61970CIM17v38’, dated ‘2020-01-21’, and includes the following significant technical changes with respect to the previous edition:
a) Added Feeder modelling;
b) Added ICCP configuration modelling;
c) Correction of issues found in interoperability testing or use of the standard;
d) Improved documentation;
e) Updated Annex A with custom extensions;
f) Added Annex B Examples of PST transformer modelling;
g) Added Annex C HVDC use cases.
Since this document is detailed and specific, we recommend that you carefully check the specified characteristics with those that are necessary for your organization.
Overhead lines - Requirements and tests for spacers
Test methods are always the first step in technology launch and implementation. But even this stage is regulated by international standards, one of which is IEC 61897: 2020.
This standard is available as IEC 61897:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61897:2020 applies to aeolian vibration dampers intended for single conductors or earth wires or conductor bundles where dampers are directly attached to each subconductor. The purchaser may adopt part(s) of this document when specifying requirements for cables different from those mentioned above (e.g. optical ground wires (OPGW), all dielectric self-supporting optical cables (ADSS)). In some cases, test procedures and test values are left to agreement between the purchaser and the supplier and are stated in the procurement contract. Annex A lists the minimum technical details to be agreed between purchaser and supplier. Throughout this document, the word “conductor” is used when the test applies to dampers for conductors or earth wires. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Consider, in addition to Stockbridge type aeolian vibration dampers, also spiral aeolian vibration dampers and elastomeric aeolian vibration dampers. b) Consider the application of dampers on high temperature conductors, specifying additional high temperature tests in clamp slip tests. c) Simplify the procedure of the damper effectiveness evaluation. d) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers. e) Include figures showing the test arrangements for the main mechanical tests.
If you are interested in purchasing this document, we recommend that you clarify with our team the possibility of using it in your business and, in case of discrepancy, select the most relevant standard.

Since the test methods cover a wide variety of industries, the number of standards is increasing every day. One of the main documents is IEC 61854: 2020.
It is available as IEC 61854:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61854:2020 applies to spacers for conductor bundles of overhead lines. It covers rigid spacers, flexible spacers and spacer dampers.
It does not apply to interphase spacers, hoop spacers and bonding spacers. This document is written to cover the line design practices and spacers most commonly used at the time of writing. There may be other spacers available for which the specific tests reported in this document may not be applicable.
In some cases, test procedures and test values are left to agreement between purchaser and supplier and are stated in the procurement contract. The purchaser is best able to evaluate the intended service conditions, which should be the basis for establishing the test severity. In Annex A, the minimum technical details to be agreed between purchaser and supplier are listed. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition: a) Consider the application of spacers on high temperature conductors specifying additional high temperature tests in clamp slip tests and for the characterization of elastic and damping properties; b) Specify as far as possible test parameters and acceptance values; c) Avoid as far as possible the alternative procedures for the same test; d) Introduce a simpler test device for the simulated short circuit current test; e) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers; f) Prescribe a different procedure for subspan oscillation tests on spacers equipped with clamps having rod attachments; g) Modify the test procedure for the aeolian vibration tests; h) Prescribe a different procedure for aeolian vibration tests on spacers equipped with clamps having rod attachments; i) Re-edit all the figures in order to make them more clear and homogeneous; j) Introduce an additional test device for the simulated short circuit current test.
