电磁兼容(EMC)—谐波电流与电压波动和闪烁限值

IEC 61000-3-2:2018+AMD1:2020 CSV Electromagnetic compatibility(EMC)-Part 3-2:Limits-Limits for harmonic current emissions (equipment input current ≤ 16 A per phase)
GB 17625.1-2012 电磁兼容 限值 谐波电流发射限值(设备每相输入电流≤16A)

THC总谐波电流(total harmonic current):2-40次谐波电流分量总有效值。
THD总谐波畸变率(total harmonic distortion):所有谐波分量有效值(2-40次谐波电流分量)与基波电流有效值之比。

IEC 61000-3-3:2013+AMD1:2017+AMD2:2021 CSV Electromagnetic compatibility (EMC) - Part 3-3: Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current ≤16 A per phase and not subject to conditional connection
GB/T 17625.2-2007 电磁兼容 限值 对每相额定电流≤16A且无条件接入的设备在公用低压供电系统中产生的电压变化、电压波动和闪烁的限值

Pst短期闪烁指示值(short-term flicker indicator):评定短时间(几分钟)闪烁的严酷程度。
Plt长期闪烁指示值(long-term flicker indicator):用连续Pst值评定长时间(几小时)内闪烁的严酷程度。
