Power-intensive industries often require lengthy cables, with some sectors utilizing cables extending hundreds or even thousands of meters into harsh environments. Long cables introduce numerous issues for motors, amplifying voltage spikes and generating higher-order harmonics. These unstable voltages can damage both cables and motors.
Variable frequency drives cause voltage distortion, common-mode voltage, peak voltage, and higher-order harmonics, leading to cable damage and premature motor insulation failure, overheating, reduced service life, and bearing damage. This also results in decreased system energy efficiency, higher failure rates, reduced production capacity, and increased costs.
