application scenarios:
In industrial manufacturing and machining workshops, protect capacitor banks from harmonic interference caused by variable-frequency equipment; in industries with concentrated rectifier loads such as steel metallurgy and electrolytic chemical plants, mitigate grid harmonics and suppress resonance; in commercial complexes and large building distribution rooms, enhance the operational stability of compensation systems; in photovoltaic and energy storage power stations, assist capacitors in achieving reactive power compensation and harmonic mitigation; in grid upgrade projects for aging industrial sites, address issues of excessive harmonics and frequent capacitor failures.
