Abstract
The hybrid circuit breaker design offers a fast low-loss operation that can be of paramount importance for the development of future meshed HVDC systems. This paper summarizes the main results obtained from a parametric analysis based on a simplified representation of both the circuit breaker and the test system. The main goals are to investigate the operation of the new device when running as a fault-current limiter and find out the influence that some breaker and system parameters (e.g. prospective short-circuit current in the test system, operation time of the mechanical switch, cable length, fault position, rated voltage of arrester) can have on the overcurrents and overvoltages that will occur during breaker operation. The results derived from this study can be useful for choosing some breaker parameters and to lesser extent for improving the breaker design.
