Predictive Maintenance of the Transmission Overhead Lines to maintain the Reliability of the Overhead Transmission Lines Network: A Utility Experience

This paper is a discussion on the brief description, experiences and key recommendations on the predictive maintenance activities implemented in the overhead transmission lines network of Dubai Electricity and Water Authority (DEWA), in Dubai in the United Arab Emirates, which significantly contributed in maintaining high reliability of the overhead line network. The core of the discussions was based from the experiences in implementation and on the results delivered which were found effective since abnormalities were anticipated allowing repairing to be done in a planned arrangement avoiding the occurrence of a forced outage event.
