HARMONIC FILTER
ABOUT PRODUCT
HANOS-Z/S SERIES
◈ Damage caused by zero harmonic current
· Neutral overcurrent/overheating may cause burnout or fire
· Communication line induced failure
· Automatic control system malfunction
· Potential rise between neutral wire and ground and control device malfunction
· ELB/MCCB/OCGR/ACB malfunction
· Emergency generator output decline or startup failure
· Noise and vibration generation
· Overheating of transformer and cable neutral wire
· Increased transformer and cable loss
· Reduction in transformer and cable transmission capacity
· Power factor reduction, condenser burnout
· Increased leakage current (Io)
◈ Why does neutral current flow more than phase current?
Zero harmonic source
· OA devices such as computers, printers, monitors, copiers, etc.
· Home appliances such as home theater, TV, air conditioner, refrigerator, etc.
· Electronic ballast, lighting control device, electronic sign, HQI lighting
· Single phase current generator, SMPS, DIMMER, charger
· Occurs in other electronic devices as well
Zero harmonic currents are scalar synthesized from the neutral wire
· Neutral current is regulated to less than 39% of phase imbalance current according to internal wiring regulations.
· Phase zero harmonics occur in the neutral line due to the inflow and overlap of harmonic currents in the neutral line.
Overcurrent flows due to scalar synthesis of current.
(3 times the phase current equivalent to the phase current)
◈ HANOS principles
· Lowers the image impedance to absorb image harmonic current.
· Increase the impedance on the power supply side to prevent harmonics from flowing into the power supply.
· Applies to systems using single-phase non-linear loads in a three-phase, four-wire distribution system.
· Excellent ability to improve load imbalance current
※ Current Technology/USA, its reduction performance is superior to that of products selected as one of the top five excellent products in the United States in 1998, and its reduction performance is superior to that of any other product in the world.
◈ Damage caused by zero harmonic current
· Neutral current (HANOS-Z: 70~90%, HANOS-S: 98% or more) reduction
· Reduce transformer and cable losses by improving
general load imbalance rate
· Increased capacity and reduced losses by reducing
transformer noise and heat
· Increased emergency generator operation efficiency
· Reduction of potential between neutral
line and ground Reduction of leakage current
· Reduce ELB/MCCB/OCGR/ACB malfunctions
· Reduce losses by increasing CABLE transmission capacity
· Reduce semiconductor device malfunctions
· Power factor improvement, condenser life extension
· Reduction of communication line induced disturbances
◈ Installation effect : 00 construction, 3ph 150A (380y220)V
HANOS-I
◈ Outline
Reduce harmonics generated from 3-phase non-linear loads to below IEEE-Std.519 management regulations.
◈ Application
3-phase 6-pulse rectifier, inverter, UPS, HVDC System, AC/DC Drivers, Elevators, etc.
◈ Characteristics
1. Significantly less than the C value of the passive filter, there is no concern about system resonance
2. Reduce harmonics to below control regulations despite load fluctuations
3. It has a smaller appearance than a passive filter or an active filter, so it's easy to install
Line Filter
(ACL : For shearing inverter)
◈ Outline
Installed at the front of the inverter to reduce harmonics generated from an inverter or rectifier using a 3-phase 6-pulse rectifier circuit and improve the power factor.
◈ Application
3-phase inverters, rectifiers, HVDC System, AC/DC Drivers, Elevators, etc.
Load Filter
(For rear end of inverter)
◈ Outline
Installed at the rear of the inverter to protect the motor from bearing noise, wear, and vibration due to rotational force eccentricity caused by torque unevenness and angle phase caused by notching.
◈ Application
3-phase inverters, HVDC System, AC/DC Drivers, Elevators, etc.
