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...

Trip Coil Signature Analysis and Interpretation for Distribution Circuit Breaker Condition Assessment and Diagnosis

A circuit breaker may be considered an ‘active link’, used to make and break an electrical circuit under conditions of varying severity. In the event of a circuit fault the circuit breaker must respond within tens of milliseconds in order to prevent damage to connected plant and safeguard personnel. As such, a circuit breaker will remain idle for the bulk of its lifetime, only being called into...

Real-time Monitoring and Assessment of Circuit Breaker Operations for Diagnostics and Control Applications

Circuit breakers (CBs) are very important elements in the power system. They are used to switch other equipment in and out of service. Circuit breakers need to be reliable since their incorrect operation can cause major issues with power system protection and control. Today’s practice in monitoring circuit breaker operation and status in real time is reduced to the use of Remote Terminal Units ...
