The two main advantages of the CBM-strategy compared with the Event Based Maintenance (EBM) and Regular Based Maintenance (RBM) strategies are: maintenance can be effectively planned; and average end of life-time of the cable and accessories is extended. CBM strategy is being driven by the fact that a lot of power companies are now either privatised or corporatised.
