Since the Electromechanical Switch Contactors does not suit for extensive switching cycle due to wear & tear, these Thyristor switching (Electronic Switching) are the most appropriate options.


System Design

Baron Dynamic 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.
Thyristor Switching provides high speed switching of Capacitor Stages. The zero crossing switching capability of Thyristor Switching module avoids problem of voltage peaks during energizing of Capacitors at high speed. The Selection of Capacitor stages with appropriate stage ratios matching the load profile provides power factor correction with high resolution.

The protection against spike current, Capacitor over load, and over Temperature is offered by forced Thyristor turn-off. It does not use semiconductor fuses as in the case of SSR, which causes nuisance flues blowing
