300A Passive Tuned Neutral Harmonic Filter

In the low-voltage power distribution system of three-phase four-wire system, with the large-scale application of power electronic devices such as LED lighting, switching power supply, uninterruptible power supply, etc., the current on the neutral line in the power distribution system is getting larger and larger. When the neutral line current is greater than the phase current, it is easy to cause the neutral line to be overloaded, the temperature rises, or even burns, and there is a major safety hazard.
After long-term analysis and research on the problem of excessive neutral current, Reton Power has developed the RT-NLF series neutral current filter device.
