The common application of Power Line Reactor Choke is with VFD. It is used in line with mains input of VFD.
Line Reactor is specified for input current and reactor inductance in mH. Most common specification for Line Reactor is %(percentage of supply voltage). This % means the voltage drop across the Line Reactor at normal application current and line frequency.
Benefits of use of Line Reactor
- Minimise overvoltage tripping of VFD due to voltage spike.
- Protect against power line surge due to in-rush current.
- Reduce the input line current harmonics and inprove the power factor of line.
- Line Reactor controls high frequency transients, voltage surges, pulse distortion and harmonics.
- 3% Line Reactor Choke is best to protect damage of VFD-component and it is best for control the power spikes and in-rush current surges and also reduce harmonics at input supply line.
