Motor Protection solution

Long cable runs driven by variable frequency drives (VFDs) can cause voltage distortion, peak over voltage, and high-order harmonics, leading to cable aging, motor insulation failure, overheating, and bearing damage. This shortens equipment lifespan, reduces system efficiency, and increases failure rates and maintenance costs.
