KDR line reactors are electrical components that help to protect 6-pulse rectifiers and power conversion devices such as variable frequency drives (VFDs). When used in conjunction with a VFD, a KDR line reactor can help reduce harmonics and protect the drive from harmful voltage spikes. KDR line reactors are recommended on the input of each VFD in multiple drive applications.
KDR reactors are constructed with durability in mind and can be used on both the input and output of a VFD. When used on the output of a drive, KDR reactors reduce voltage distortion at the motor terminals extending the service life and minimizing insulation stress of any motor.
Variable frequency drives (VFD) are beneficial to a wide range of applications, but contain a power conversion process that creates current and voltage distortion, known as harmonics.
Issues caused by harmonics may include:
- Transformer and distribution equipment overheating
- Random breaker tripping
- Sensitive equipment failure
- Poor power factor
Advantages
- Extend the life of the motor on the output of the VFD
- Protect other equipment on the line from operational issues caused by voltage distortion
- Dramatically increase drive uptime by reducing the likelihood of the drive tripping
- Improve power factor
- Reduce motor heating and audible noise
- Increase system productivity
