Review of Condition-Based Monitoring Techniques for Electrical and Industrial Assets to Promote Digitalization Strategies for Utilities

Asset reliability and availability are two of the most important criteria in any industry. In the modern power systems, the requirement for continuous and quality power is more stringent as every industry depends on the same. In this regard, advanced maintenance techniques like Condition Based Maintenance (CBM) and Prognostics Health Management (PHM) have become increasingly popular. The paper explores CBM and PHM techniques, as real-time monitoring solutions that assist in condition assessment & optimization, remaining life prediction, proactive maintenance and operational planning. The paper segregates electrical utilities based on generation, transmission & distribution segments and identifies the important assets in each segment, further diving into the failure modes, identifying parameters for monitoring and exploring techniques for CBM and PHM. The paper also highlights the increase in demand for CBM solutions with projections till 2029.
