Zero Sequence Filter(zsf)

We are offering our client an excellent quality range of Zero Sequence Filter(ZSF)
* Applications
Applicable Loads Computer, OA equipments, Electronic fluorescent lamp, Single Phase SCR heater and UPS etc. Applicable System Single phase nonlinear loads on Three phase four wire system Applicable Locations Office/Commercial building, School, Shopping Mall, Department store, Apartment, Hospital, Factory etc.
* Benefits
Reduce Line Current The ZSF can reduce rms value of line current by reducing zero sequence harmonic current that is produced by single phase non-linear loads in three phase four wire system. Reduce Neutral Current The zero sequence current in line make a large neutral harmonic current by trebling.
The ZSF can reduce this large neutral current up to 90% depend on ZSF location. Meet IEEE Std.519-1992 The ZSF enable most single phase non-linear loads to comply with both the voltage and current distortion limits of IEEE Std.519-1992 and other international limits such as AS-2279, EN61000-3-4, and BS G5/4.
* Solve Power Quality Problems
Protect loss and reduce capacity because of circulating effects by zero sequence harmonic current in transformer.
Protect heating and loss of line and neutral cable that is effected by zero sequence harmonic current.
Reduce unbalance of line current.
Improve power factor.
Reduce system loss.
Reduce K-factor rating of load current at main transformer.
