Abstract
This paper introduces an interactive visualization interface prototype tailored for electrical power grid system planners and analysts to facilitate the exploration of historical outage data and gain actionable insights. With the advent of smart sensors, data generation has exponentially increased. As the amount of data has significantly grown, so has the need to effectively monitor it. Our prototype addresses this challenge by seamlessly integrating heterogeneous datasets such as GIS, AMI, and OMS. Our interface is designed to empower system planners and analysts in assessing the performance of distribution systems, focusing on circuit efficiency and outage events. This paper describes the functionalities of the visualization interface and presents its example usage scenarios.
