DC interruption characteristic of vacuum circuit breaker
Electrical Engineering in Japan, 2005 AbstractA high‐speed vacuum circuit breaker (HSVCB) has been investigated. HSVCB makes high‐frequency current superimposed on a fault current so that the current is forced to be zero and is interrupted. Its interruption performance is considered to be dependent on the rate of change of the current (di/dt). As a fundamental research, we investigated the

T-Type Modular DC Circuit Breaker (T-Breaker) as a Compensator for Future DC Grids
IEEE Access, 2023 When ac and dc microgrids get exposed to load power changes or voltage transients, instability could occur owing to constant power loads’ (CPLs) behaviour. CPL has the negative impedance behaviour which is the reason behind such instability. A flexible alternating current transmission system (FACTS) devices are used in ac grid to help improve ...
