Investigating Impacts of Sustainable Repair Time and Circuit Breaker Model on Meshed Distribution Networks Reliability Assessment
Generally, the failure rate and the repair time of system components are constant parameters in reliability assessment of electric distribution systems. A failure of component is resulted from failing in the operation or overloading. In addition, there exist cases where, the repair times of components are small and tolerable from customer point of view. Thus, tolerable repair times may be overl...
متن کاملPower system monitoring based on relay and circuit breaker information
In this paper we develop monitoring schemes that are able to detect and identify failures in power transmission lines by analyzing binary status information from relays and circuit breakers. The approach, which is based on Petri net models, requires very simple calculations (linear checks) during execution time and allows for concurrent/incremental processing of the information as it arrives at...

متن کاملInvestigation of Circuit Breaker Dielectric Performance
The violent event of a short-circuit leads to short-term exposure of circuit breaker components to extremely high current, causing thermal degradation, vaporization and deformation of some components and the deposition of surface contaminants. After short-circuit, the leakage current carried by the breaker, when voltage is applied, increases dramatically but must remain below a certain threshol...
متن کاملAutomated Analysis of Circuit Breaker Operation
In this paper a new approach to the analysis of test results for circuit breakers is discussed. It is implemented through new software called Automated Circuit Breaker Monitoring system ACBM. The circuit breaker performance is evaluated based on the analysis of Digital Fault Recorder (DFR) recordings taken from circuit breaker control circuitry. This paper describes the testing procedure and us...
