Dual Voltage Control Schemes Control one or two capacitor banks or reactors. Also includes voltage control instability detection logic, logic inputs to supervise voltage control scheme, four voltage control timers, and loss of potential logic with timer. Eleven-Cycle Event Reporting Quick validation of settings and reporting of reclosures. Protect and control grounded-wye shunt capacitor banks. Sensitive differential protection detects individual blown fuses, even in large banks.
Protection is independent of system operation conditions, e.g., unbalanced and external faults.
Accommodate switched capacitor banks and reactors with control voltage settings. Include a two-step control scheme for adaptive switching.
