Asset Management Based on Condition Monitoring and Risk Evaluation

Equipment condition monitoring technologies have been rapidly developed with the progress of electronic devices and information technology. This chapter presents asset management methods based on both equipment condition monitoring and system risk evaluation. Two management strategies are presented. One is the maintenance strategy of nonaged overhead lines and the other is the replacement strategy of aged transformers. In the case of nonaged overhead lines, the key is to build the model for the relationship between condition monitoring information and failure frequency of lines, whereas in the case of aged transformers, the key is to build the model for the relationship between aging condition measurements and unavailability due to aging failure of transformer.
