Dynamic Condition Assessment of Substation Equipment through an Asset Performance Management System

In recent years, there has been a push towards substation asset digitization with an increase in the availability of intelligent electronic devices (IEDs) in the market. Utilities and industrial establishments are considering a transition from traditional time-based maintenance (TBM) to condition-based maintenance (CBM) based on real-time asset monitoring and condition assessment. In this background, the development of an Asset Performance Management (APM) system comprising of equipment sensors, a data pipeline, intelligent models, and a human-machine interface (HMI) allows for relevant planning and real-time results to be organized and visualized across a centralized platform. This paper presents the framework for dynamic monitoring and condition assessment of station equipment, such as power transformers, power cables, circuit breakers, and switchgear, to respond in advance to potential emerging risks and avoid catastrophic failures. Within the scope of this study, the implementation of an APM system, specific to power transformers, has also been demonstrated.
