Power Factor Capacitors Can Make Factory Harmonics Worse: What Engineers Must Check

Adding power-factor correction capacitors to a factory can improve electrical efficiency at the distribution level, but it can also create a serious power-quality problem. In facilities with variable frequency drives (VFDs) and other electronic equipment, capacitor banks may amplify existing harmonic currents instead of improving overall electrical performance. The risk Continue Reading

OEE Can Improve While Factory Output Stays Flat: How to Find the Real Production Bottleneck

Improving a machine’s Overall Equipment Effectiveness (OEE) does not necessarily increase the number of finished products a factory can deliver. If another process is already limiting production, making a faster machine even more efficient may simply create additional work-in-process inventory. This distinction matters when manufacturers prioritize maintenance projects, justify automation Continue Reading

Regenerative Servo Drives: Why Recovered Braking Energy Does Not Guarantee Big Electricity Savings

Regenerative servo drives can reduce industrial electricity consumption by recovering energy when motors slow down or when loads drive the motors. However, the amount of energy generated during braking is not necessarily the amount of electricity a factory will save. Some braking energy is lost through friction and electrical conversion. Continue Reading
