ZYH-SPH series Passive Harmonic Filter 下载PDF产品手册>>
The Harmonic——a Growing Problem Today's electrical networks and plants are under much more streess that for the increasing use of electric equipment which generate harmonics in particulare the odd harmonic.This harmonic can generate exceptionally high neutral currents wich can often exceed the phase current.

The Solution ——The Harmonic Filter
We have developed the harmonic filter for decreased the harmonic interference of 3、5、7、9ect.and more.These harmonic filters can makevoltage and current become sine wave ,which will improve the eletricity condition and power factor.Once the filter is installed,machine interruptions decrease and process reliability improves.The filter also eliminates the harmonic in phase conductors and power consumption is smaller.

Appling automatic switch without touching,continuously and frequently switching filter without decreasing lifetime of capacitors.
Fleetly checking system and compensating quickly and realtimly according the requirement of system
Designing for the cutomer special,better filtering effect ,power factor greater than 0.95 after compensating .
Quick dynamic response ,less than 20ms
Without transient impulse when switching ,without surge ,switching without discharging
Complete protective functions including various protection and excellent reliability .
With low maintenance quantity and so low run cost

TNC system
