Bank-Specific Voltage Matching:Rated to match the voltage levels of shunt compensation capacitor banks, ensuring they provide precise protection without causing unnecessary energy loss or interference with the banks’ reactive power compensation function.
High Surge Handling Capacity:Designed to absorb large amounts of energy from severe transients, such as those from direct lightning strikes or capacitor bank switching surges, effectively mitigating the impact to protect capacitor elements from breakdown.
Fast Response to Transients:Equipped with high-performance metal oxide varistors (MOVs) that respond in microseconds to overvoltage events, critical for capacitor banks which are highly sensitive to voltage spikes even of short duration.
Resistance to Harmonic Stresses:Able to withstand harmonic currents and voltages commonly present in grids with shunt capacitors, ensuring stable performance without degradation from long-term exposure to harmonic distortion.
Durable Environmental Protection:Housed in robust materials like composite silicone rubber or porcelain, offering strong resistance to moisture, pollution, UV radiation, and extreme temperatures, suitable for both indoor and outdoor installations.
Low Leakage Current:Maintain minimal leakage current during normal operation, reducing power loss and preventing excessive heating, which helps maintain the efficiency of the capacitor bank system.
Compatibility with Bank Configurations:Designed to integrate seamlessly with various shunt capacitor bank configurations, including single-star, double-star, or delta arrangements, adapting to different grid requirements.
Compliance with Industry Standards:Meet international standards such as IEC 60099-4 and IEEE C62.11, ensuring they undergo rigorous testing for reliability, safety, and performance, compatible with global power system setups.
