Neutral Current Eliminator, also known as a Zero Sequence Filter, is a high-tech energy-saving product designed to address equipment malfunctions and safety hazards caused by excessive neutral current in electrical equipment across various industries during balanced three-phase loads.


Zero-Phase Current Eliminator Features:


+ Significantly reduces the current in the neutral wire, eliminating fire hazards caused by excessive neutral wire current.
+ Capable of filtering out 3n harmonics simultaneously (LC filters can only filter out harmonics at specific frequencies).
Without filter capacitors and electronic components, like a dry-type transformer, it has a lifespan of up to twenty years.
+ Effectively prevents harmonic amplification; Neutral line filter
Avoid harmonic interference with precision equipment (such as computer crashes), which can lead to unnecessary losses.
+ Effectively protects capacitors from overloading in reactive power compensation, extending their service life; significantly reduces transformer iron and copper losses, achieving energy savings of over 10%.
Increase transformer utilization rate (due to excessive neutral current, some transformers have an efficiency of less than 30%);
+ Prevent zero-sequence protection false operation and eliminate economic losses caused by false operation.
