Standards Development

Scope

This part of IEC 61000 is concerned with the limitation of voltage fluctuations and flicker impressed
on the public low-voltage network by energy producing systems. The scope includes equipment with
rated current less than or equal to 75 A per phase, who's primary purpose is to produce electrical
energy into the low voltage public supply.

Equipment who's primary purposes is not energy production, but may deliver energy to the public
supply only under specific conditions, is excluded from the scope. Examples of excluded equipment
are regenerative motor control, plug-in EV & hybrid EV, and standby & emergency generators. This
part of IEC 61000 is applicable to electrical and electronic equipment intended to be connected to
public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz.

This document defines:

a) requirements and emission limits for equipment and

b) methods for type tests.

Tests according to this document are type tests of complete pieces of equipment.
Conformity of this standard can also be determined by validated simulations.

Purpose

More and more pieces of equipment producing electrical energy are directly connected to the public low voltage grid and may cause additional voltage fluctation and flicker. This TS intends to close the gap by introducing requirements and emission limits together with appropriate test methods for type tests (according to the proposed scope).
