Harmonics & CMC / Bearing Fluting
Many commercial applications being used in industry today have non-linear electrical loads. Common examples of these applications are variable frequency drives, non-incandescent bulbs, computers, uninterruptible power supplies, copy machines, battery charges, and many more. While they have many benefits, these applications also have detrimental side effects caused by the Common Mode Currents and harmonics they produce. Examples of these are
- Shortened electric motor live
- Transformer and distribution equipment overheating
- Sensitive equipment communication issues
- Poor power factor
- Random breaker tripping and ghost shutdowns
- IEEE-519 non-compliance
Wolters has compiled a set of bearing fluting offerings targeted on mitigating the CMCs and Harmonics.
Common Mode Current (CMC)
CoolBLUE’s innovative design uses nanocrystalline inductive absorbers, which are more effective than other soft magnetic materials like ferrites due to their superior magnetic properties.
Harmonics
IEE-519 2014 sets limits responsibilities on the electric power end user to how much harmonic current is being produced to protect the power distribution components.
Cable Shield Head Adapter
The BAKC Cable Shield Head Adapter is a product used when the shielded VFD cable between a VFD and its motor is required to be cut and re-terminated.
Cable Shield Plate Adapter – Terminal Block
Use BAKC Cable Shield Plate Adapter – Terminal Block product in the electrical panel enclosure where convenient field termination of VFD shielded cable can be made with terminal block connections for the motor load and ground wires while maximizing the shield surface area continuity.
