IEC/TS 62257-7-1:2010(E) specifies the general requirements for the design and the safety of generators used in decentralized rural electrification systems. Provides requirements for ELV and LV PV arrays. Particular attention must be paid to voltage level, as this is important for safety reasons and has an influence on protective measures and on the skill and ability level of operators. The main technical changes with regard to the previous edition are the following: - this new version is focused on small PV generators up to 100 kWp; - it provides case studies.

IEC TS 62257-6:2015(E) describes the various rules to be applied for acceptance, operation, maintenance and replacement of decentralized rural electrification systems which are designed to supply electric power for sites which are not connected to a large interconnected system, or a national grid, in order to meet basic needs. This technical specification proposes a methodology to achieve the best technical and economic conditions for acceptance, operation, maintenance and replacement of equipment and complete system life cycle. The main technical changes with regard to the previous edition are as follows: - redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V; - removal of the limitation of 100 kVA system size.

IEC TS 62257-5:2015(E) specifies the general requirements for the protection of persons and equipment against electrical hazards to be applied in decentralised rural electrification systems. Requirements dealing with protection against electric shock are based on basic rules from IEC 61140 and IEC 60364. Decentralized Rural Electrification Systems are designed to supply electric power for sites which are not connected to a large interconnected system, or a national grid, in order to meet basic needs. Examples of such sites: isolated dwellings, village houses, community services, economic activities, etc. The main technical changes with regard to the previous edition are as follows: - redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V; - removal of the limitation of 100 kVA system size.

IEC TS 62257-4:2015(E) provides a method for describing the results to be achieved by the electrification system independently of the technical solutions that could be implemented. The purpose is to provide a method to assist project contractors and project developers to select and design the electrification system for isolated sites while matching the identified needs, such as those described in IEC TS 62257-2. The main technical changes with regard to the previous edition are as follows: - redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V; - removal of the limitation of 100 kVA system size.

IEC TS 62257-3:2015(E) provides information on the responsibilities involved in the implementation of rural power systems. More particularly it covers: - contractual relationships to be built between the different participants to a project; - the relevant tests to be applied to renewable energy and hybrid electrification systems; - quality assurance principles to be implemented; - requirements for recycling and protection of the environment. The main technical changes with regard to the previous edition are as follows: - redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V; - removal of the limitation of 100 kVA system size.

IEC TS 62257-2:2015(E) proposes a methodological approach for the setting up and carrying out of socio-economic studies as part of the framework of decentralized rural electrification projects. It is addressed to project teams and in particular to experts in charge of socio-economic studies in international projects. This technical specification also provides some structures as technical solutions that could be recommended, depending on the qualitative and quantitative energy demands, consistent with the needs and financial situation of the customers. The main technical changes with regard to the previous edition are as follows: - redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V; - removal of the limitation of 100 kVA system size.

IEC TS 62257-12-1:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 62257-12-1:2020 establishes the framework for creating a product specification for lamps and lighting appliances to serve as the basis for evaluating quality for a particular context. Product specifications include minimum requirements for quality standards, warranty requirements, and/or performance criteria. Products are compared to specifications based on test results and other information about the product. The product specification framework is flexible and can accommodate the goals of diverse organizations and institutions. This third edition cancels and replaces the second edition published in 2015. This edition includes the following significant technical changes with respect to the previous edition. - Annex A and Annex B were combined into a single Annex A to eliminate duplicate tables and simplify the document.
