The Fenarro TBB High Voltage Reactive Power Compensation Cabinet is an intelligent system designed to optimize the efficiency and stability of 10kV electrical networks. By automatically switching capacitor banks in response to real-time reactive power demand, it corrects lagging power factor, reduces line losses, frees up system capacity, and improves voltage regulation. The system incorporates advanced protection features like inrush current limiting reactors, discharge devices, and comprehensive microprocessor-based relays that guard against overvoltage, overcurrent, unbalance, and harmonics. This results in direct energy savings, reduced utility penalties, and extended equipment life for end-users.
Automatic Control: Microprocessor controller with multiple switching strategies (e.g., VAR, PF, time-based).
Advanced Protection: Includes harmonic suppression reactors, fuses, surge arresters, and relay-based protection.
Modular Design: Capacitor steps can be easily added or reconfigured as load profiles change.
Safety Compliant: Meets all safety requirements of GB/T30841-2014 and GB50227-2017.
Remote Monitoring: Communication options (RS485, Ethernet) for integration into plant SCADA.
