Depending on the load variation the PFI Panel automatically switches the externally/internally installed capacitor ON or OFF to bring it to the desired or preset value of power factor.

This integrated management of the load power factor results in enhanced power quality as well as other benefits like:

• Optimum utilization of installed capacitor bank
• Optimum utilization of demand
• Lower maintenance costs
• Increased efficiencies
• Higher capacitor and contactor life

Features
The PFI Panels come with a No-volt release feature to immediately disconnect all capacitors in the event of power failures, detection and display of over-voltage, over-current, harmonics and power factor under compensation

• Compact, standalone / modular units
• Micro processor Power Factor Relay
• Capacitor duty contactors
• Choice of the type of capacitor
• Low Watt loss
• Short pay-back period
• Digital indication of power factor, current, THD%
• Automatic self-adjustment to any kVAr value
• Monitoring of harmonics
• Over-voltage protection
• Optional communication port RS 485 with software

Structural Design of the PFI Panel

Capacitor Bank Sizes
The PFI Panel is designed in a binary sequence so that a large number of combinations are available for a given set of contactors. An intelligent banking pattern provides all the combinations needed to achieve the preset target without hunting, thereby increasing the life of the contactors and capacitors.

Switching In & Switching Out
Thyristor switching provides rapid ON/OFF switching of capacitors and quick achievement of set PF targets. This also enhances the contactors and capacitors life.

Models
Conzerv PFI Panels are available for ratings from 30 kVAr to 500 kVAr.
