Reliability-centered power line management-inspection process, measurement techniques and data management considerations

While methods and practices for maintaining the reliability of overhead line systems may differ between US and UK electric utilities, there are more similarities than differences. Impending deregulation has forced more immediate changes within the industry to evaluate current design and maintenance practices to achieve the most from available assets at the least cost. As utility line managers desire more quantitative inspection information by which to optimize required maintenance and forecast line performance and maintenance needs, line inspectors are required to utilize state-of-the-art tools and techniques capable of providing such information. The intent of this paper is to review tools and techniques which can enhance the data obtained during the inspection process for overhead wood pole lines. The ability to consistently collect and report quantitative data is a critical component of the reliability-centered management (RCM) approach to overhead line management.
