11. Equipment approach
The standards contains methodology of emission test and limits for particular kind of
equipment
Limits for voltage changes - emission test - definitions
IEC 61000-3-3 Electromagnetic compatibility (EMC) – Part 3-3: Limits – Limitation of voltage
changes, voltage fluctuations and flicker in public low-voltage supply systems. Equipment
with rated current ≤ 16 A per phase and not subject to conditional connection.
IEC 61000-3-11 Electromagnetic compatibility (EMC) – Part 3-11: Limits – Limitation of voltage
changes, voltage fluctuations and flicker in public low-voltage supply systems. Equipment
with rated current ≤ 75 A per phase and not subject to conditional connection.
