Risk-Based Maintenance Approach: A Case of Circuit Breaker Condition Based Monitoring
نویسنده
چکیده
-This paper presents an overview of resource optimization approach for transmission system maintenance selection and scheduling. The approach is based on failure rate estimation and risk reduction calculation followed by resource optimization. It also presents probabilistic models developed for circuit breakers and power transformers. An effort is made to quantify the effect of maintenance using the circuit breaker monitor’s data.

Integrated Preventive and Predictive Maintenance Markov Model for Circuit Breakers Equipped With Condition Monitoring
The Circuit Breaker (CB) is one of the most important equipment in power systems. CB must operate reliably to protect power systems as well as to perform tasks such as load disconnection, normal interruption, and fault current interruption. Therefore, the reliable operation of CB can affect the security and stability of power network. In this paper, effects of Condition Monitoring (CM) of CB on...

متن کاملMultiresolution Based Pattern Recognition Approach for Condition Monitoring of Switchgear
A new multiresolution based pattern recognition approach is proposed for fault diagnosis of distribution switchgear. The wavelet transform is used to extract the key features from the vibration spectra following circuit breaker operation. These features are then used to plot a 2-D diagram or condition map. This map displays clearly the actual condition of the circuit breaker and it can also be ...
متن کاملAvailability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval
Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
