Schneider Electric's Varlogic controller permanently monitors the plant's reactive power and controls the connecting and disconnecting of capacitor stages to achieve the targeted power factor. If overvoltage, low power factor, or overcompensation occur, the alarm relay will activate. Users can set the power factor from 0.85 inductive to 1. The new control algorithm is designed to reduce the number of switching operations and quickly achieve the targeted power factor.
Performance
- Permanent monitoring of the network and equipment.
- Information provided about equipment status.
- New control algorithm designed to reduce the number of switching operations and quickly attain the targeted power factor.
Simplicity
- Simplified programming and possibility of intelligent self set-up.
- Ergonomic layout of control buttons.
- Quick and simple mounting and wiring.
- A Special menu allows controller self-configuration.
User-friendliness the large display allows :
- Direct viewing of installation electrical information and capacitor stage condition.
- Direct reading of set-up configuration.
- Intuitive browsing in the various menus (indication, commissioning, configuration).
- Alarm indication.
Monitoring and Protection
Alarms
- Should an anomaly occur on the network or the capacitor bank, alarms are indicated on the screen and alarm contact is initiated.
- The alarm message is maintained on the screen once the fault clears until it is manually removed.
Protection
- If necessary, the capacitor steps are automatically disconnected to protect the equipment.
