The Automatic Power Factor Correction Systems are Optimal Solution for
Varying Load Patterns demanding changing Reactive Power Compensation
- Avoidance of problems due to leading PF conditions by Fixed Compensation
- Economic Solution by single Centralized Power Factor Correction System
System Design
Baron Automatic Power Factor Correction System is unique with its Custom Based Design, based on the Load Study Conducted on site with High Speed Power Quality Analyzer with recording interval selected as appropriate to the study, depending on the Loading pattern.
The System is basically designed as a series RLC Circuit to suppress the transient inrush current, while injecting reactive current. Its Components Selection is critical due to the inherent operating parameters of the Capacitors which draws high inrush current during switching and while opening out. The Electrical charges remains in the capacitor thereby building up the Restriking Voltage. This characteristics of the Capacitors needs careful study and selection of the correct components to ensure long life for the total system.
The Choice of Capacitor Duty Contactors with Damping resistors provide protection from inrush current during switching. The Coil Wound Inductors provide additional protection from short time high current peaks. The Sequential Cyclic Switching of Capacitors with preset time delay for safe discharge of capacitors, increases the life of capacitors and avoids problems rooting from voltage peaks while energizing the charged capacitors at Sinusoidal Peak instants of Supply Voltage.
The selection of Capacitor stages with appropriate stage ratios matching the load profile provides Power factor Correction with High Resolution.
