Recommendations for renewable energy and hybrid systems for rural electrification - Part 5: Protection against electrical hazards
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.
This publication is to be read in conjunction with IEC 62257 series.
