1. General
Increasing use of computer and electric home appliance, the neutral current zero sequence
harmonic in line make variety types of disturbances in system.
ZSF(Zero Sequence Filter) is easy to install with electric accessories and
it can reduce this large neutral current up to 90% depending on the installed position.
2. The problems of Zero Sequence harmonics
•Trip the circuit breaker due to overcurrent
•
•
3. Application
•Applicable load : C omputer, OA appliance, Electronic fluorescent lamp, Single Phase SCR heater and
•Applicable system : Single phase nonlinear loads on Three phase four wire systerm
•Applicable place : Office/Commercial Building, School, Apartment, Department, Factory, Medical center etc.
〉
•Neutral impedence adjuster upon request
•Easy to Install
•Increasing power quality
〉
•Protect heating and loss of line and neutral cable that is effected by zero sequence harmonic current
•Reduce unbalance of line current
•Protect overinvestment by increasing capacity
•Reduce K-factor rating of load current at main transformer.
