Capacitor banks are widely used for reactive power compensation and voltage regulation in systems due to their low capacity cost, flexible operation, and convenient maintenance. Due to the complex operating conditions and long-term impact of various adverse factors, component breakdown faults will inevitably occur inside the capacitor bank. After a …
To assess the capability of the capacitor bank circuit-breaker to open after a fault between the inductor and the capacitor bank, the TRV was analyzed with EMTP®. The rated TRV envelope was derived from IEC 62271-100 (or IEEE C37.06) and compared to the prospective TRV simulated using the EMTP® breaker for TRV device.
