Three Phase line Reactors and Output Reactors Compatible to ABB Inverter
Line reactors are used for preventing harmonics from being generate don the mains supply from inverter sands witch-mode power supplies. Line reactors help to keep equipment running longer by absorbing many of the power disturbances which otherwise damage motors and drives. Line Reactors Increase Drive Reliability
Its main characteristics are as below:
1. Minimize catastrophic drive failures due to transient over-voltages
2. Minimize nuisance over-voltage trips due to line transients:
(1)Utility power factor correction
(2)Switching large AC motor loads
(3)Switching large transformers
(4)High AC line conditions
3. Minimize line-side fuse operation during unsymmetrical voltage sags:
(1)Utility system line-to-ground faults
(2)Unbalanced phase currents
4. Reduce harmonics
5. Improve effective power factor
Use a reactor:
(1)To add Line Impedance.
(2)To provide some light buffering against low magnitude line spikes.
(3)To reducing Harmonics (When no link choke is present).
(4)To compensating for a low inductance motor.
(5)Only as part of a filter for reflected wave reduction.
