SANS 61000-3-12-2009 电磁兼容性(EMC).第3-12部分:限值.与每相输入电流大于16 A和小于或等于75 A的公用低压系统连接的设备产生的谐波电流
Electromagnetic compatibility (EMC) Part 3-12: Limits - Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16 A and <=75 A per phase
Deals with the limitation of harmonic currents injected into the public supply system. Applies to equipment intended to be connected to low-voltage systems interfacing with the public supply at the low-voltage level.
