High performance controlled switching vacuum circuit breaker enables fast reclosing on capacitor bank - breakthrough in reactive power compensation

Today the decentralized power generation (wind farms and photovoltaic plants) is growing more and more. Medium voltage capacitor banks are crucial to assure network stability, reliability, and reactive power compensation. The recent releases of high-performance synchronized vacuum circuit breakers for capacitor switching applications overcome technical challenges like inrush currents, prestrikes and restrikes. These features allow to extend the lifetime of the whole asset, manage the network reducing the need of components for mitigating transients and synergies with other technologies for managing loads transitions (e.g. Static VAR Compensator).
