Third Harmonic Isolation Filter TFA
TFA三次谐波隔离滤波器
In installations with 3rd harmonic generation loads, the current through the neutral cable can be higher than the one in the phases, even in case of balanced loads.
在具有三次谐波产生负载的安装中,即使在平衡负载的情况下,通过中性电缆的电流也可以高于相中的电流。
The most proper solution for these problems is to use a specific equipment for the 3rd harmonic filtering, consisting basically in a three-phase isolating transformer, delta-star connected, that completely eliminates the 3rd harmonic current, plus a passive filter which reduces the 5th harmonic.
对这些问题最合适的解决方案是使用特定设备进行三次谐波滤波,包括三相隔离变压器,三角形星形连接,完全消除三次谐波电流,以及减少第五次谐波电流的无源滤波器谐波。
