Page Count: 86
ICS Code (Solar energy engineering): 27.160
scope:

This part of IEC 62257 specifies the general requirements for the design and safety of generators used in decentralized rural electrification systems.

The earthing systems of the exposed conductive parts and neutral earthing systems which are considered in this technical specification are those specified in IEC 62257 series for IES (see IEC 62257-9-3 and IEC 62257-9-4) and CES (IEC 62257-9-2).

This technical specification contains requirements for ELV and LV PV arrays (see Table 1). 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 people operating the systems.

For the sake of completeness, this technical specification gives requirements for d.c. voltages below and above 120 V.

The aim is to provide safety and fire protection requirements for:

− uninformed persons, including owner(s)/occupier(s) and users of the premises where photovoltaic arrays are installed;

− informed workers (e.g. electricians) working on these systems; and

− emergency workers (for example fire fighters).

For installation of PV arrays see IEC 60364-7-712.
