The device uses non-reclosing circuit breakers, zinc oxide surge arresters and series reactors to effectively limit switching overvoltage, harmonics and inrush current. With dedicated fuses and relay protection, it safeguards single capacitors, internal faults of capacitor banks, system overvoltage/undervoltage, busbar phase-to-phase short circuits and overcurrent. Mainly applied in steel, mining, petroleum, power and other industries.
