PD IEC/TS 62257-6:2015

What is PD IEC/TS 62257-6 - Decentralized Rural Electrification Systems operation about? 

The IEC 62257 series covers various aspects of recommendations for renewable energy and hybrid systems for rural electrification. 

PD IEC/TS 62257-6 is the sixth part of the IEC 62257 series which is a technical specification, intends to describe the various rules to be applied for acceptance, operation, maintenance, and replacement (AOMR) of decentralized rural electrification systems (DRES) 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. 

The majority of these sites are: 

• Isolated dwellings 
• Village houses 
• Community services (public lighting, pumping, health centres, places of worship or cultural 
• Activities, administrative buildings, etc 
• Economic activities (workshops, micro-industry, etc.) 

PD IEC/TS 62257-6 does not substitute for technical manuals provided by manufacturers for each equipment. The complexity of the system and application will dictate the level of required AOMR documentation. 

Who is PD IEC/TS 62257-6 - Decentralized Rural Electrification Systems operation for? 

PD IEC/TS 62257-6 on Decentralized Rural Electrification Systems operation is useful for: 

• Relevant government / municipal authorities 
• Community leaders 
• Project managers 
• Rural electrification projects developers 
• Rural electrification project implementers 
• Contractors / supervisors / installers 

PD IEC/TS 62257-5 is also relevant for the community for whom the project is implemented. 

Why should you use PD IEC/TS 62257-6 - Decentralized Rural Electrification Systems operation? 

Hybrid power systems offer solutions for rural electrification where power supply may be inconsistent. PD IEC/TS 62257-6 proposes a methodology to for suitable technical and economic conditions for acceptance, operation, maintenance, and replacement of equipment and complete system life cycle that provides you long service life for renewable energy and hybrid systems for rural electrification.  

PD IEC TS 62257-6 provides you guidance on renewable energy and hybrid systems for rural electrification products in terms of selecting the correct system for the right area, designing the system, and operating and maintaining the system. 

PD IEC TS 62257-6 guidelines are a step towards better, cost-effective, and more sustainable facilities for rural communities. PD IEC TS 62257-6 assists in promoting the use of renewable energies in rural electrification for developing countries. 

What’s changed since the last update? 

PD IEC/TS 62257-6:2015 supersedes DD IEC/TS 62257-6:2005 which is withdrawn. PD IEC/TS 62257-6:2015 includes some technical changes with respect to DD IEC/TS 62257-6:2005. These include: 

• Redefine the maximum AC voltage from 500 V to 1 000 V as well as the maximum DC voltage from 750 V to 1 500 V 
• Removal of the limitation of the 100 kVA system size. Hence the removal of the word “small” with regard to the title and related references in PD IEC/TS 62257-6:2015
